It is the fourth feature-length live-action/animation hybrid film to feature Looney Tunes characters, after (1988),  (1996), and  (2003), and like Space Jam and Looney Tunes: Back in Action, it is a combination of live-action and traditional hand drawn 2D animation with some CGI effects.

Plot
The prologue of the movie shows test footage of a live action island showing photorealistic CGI versions of the Flock and the Pigs duking it out against each other in an all-out war, but it is interrupted by Bomb, who is sick and tired of those live-action/CGI adaptations based on cartoons, starts telling the audience that Warner Bros. must be dense. The Flock are then seen going to the Warner Bros. studio, with several cartoon characters, who are seen going on strike, helping them get there, as they angrily lash out at Thaddeus Plotz and the Warner Bros., demanding that their movie must be traditionally-animated. Plotz rudely refuses to do that, because live-action films based on cartoons make more money and calls a security guard to throw them out of the studio. Out of retaliation, Chuck calls Yosemite Sam that they've been hornswoggled and bamboozled that their movie is going to be in live-action, which the latter furiously comes in and threatens to shoot Plotz with his six-shooter if he doesn't turn the flock's movie to be fully animated. With complete regret and fear, Thaddeus Plotz quickly and promptly accepts their request to make their movie fully animated. 3 years later, we see The Flock and the rest of the Toons gathering for the first screening of the Angry Birds' first 2D-animated movie.

The movie begins as the Pigs and the Flock invite every single Toon in Toontown to share a gigantic feast at the First Annual All-Toon Companionship Festival, a time when the Flock, the cartoon characters, and the Pigs play fun games, crazy rides, and activities over Piggy Island. On his way, Bomb brings the Eggs along with him. Meanwhile, Edgar Baconhooves, the chef of pig city, complains about his failures to his lackeys, Marf, El Porkador, Frank, Professor Percy Pigsworth, Jeff McBacon, Gramps, being unable to steal the eggs. When Jeff McBacon points out plan "105", a scheme which he has yet to attempt, Edgar, seeing a reason to be optimistic, decides to implement it and get revenge on the Flock. Professor Percy has constructed a beacon. Edgar makes his final preparations, getting ready to hook Bomb's anger energy-infused feather up to the beacon and see who will come to investigate his signal. However, the moment Edgar connects the feather, an energy pulse extends far into space. After a montage of the Flock and the Toons having fun, the festivities are interrupted by an invasion of monstrous crows commanded by the villainous crow Baron Harmful (Tim Curry), the leader of Crow Island, and his cohorts, Don Bacon and Patsy, who use explosive sapphire orbs to obliterate the entire Pig City to a complete wasteland. The Flock, the toons, and the pigs go into Hal's underground bunker before they're destroyed. During some time, Hal begins studying on the liquid encased in one of the orbs, which is revealed to be the dip, a sickly green, ghastly chemical mixture of turpentine, acetone and benzene. Meanwhile, Edgar manages to negotiate with Baron Harmful to team up with him to foil the Angry Birds and enlists him to steal the eggs by force.

After making sure that Baron Harmful is gone, his voice echos, stating that he shall take something of great value to them. While not concerned at first, The Flock then realized that Baron Harmful has indeed taken something of great value to them; the Eggs, much to their shock. Baron Harmful laughs as he flies off to his blimp with the eggs, leaving the entire Flock in Piggy Island alone, devastated, with Bomb becoming extremely angered. After a pep talk with Red, Hal, and Chuck, Bomb rallies his flock to retrieve their eggs and save Piggy Island. After given missions from the Mighty Eagle, The Flock construct a boat, bringing their slingshot, and embark on a journey.

Back in Piggy Island, Baron Harmful attempts to bring the toons out by tapping the tune, Shave and a Haircut. Unable to resist that tune, Roger Rabbit bursts out of the bunker, and the rest of the toons then got captured by Baron Harmful. Edgar successfully usurps King Matthew Smoothcheeks when he finishes turning Piggy Island into his empire, as he transforms Pig City into "Swinetopia.". In the throne room, Edgar communicates with King Julian Smooothcheeks I via walkie talkies, who sees that he has finally got the eggs. When King Smoothcheeks I informs him that the Flock are attempting to get reinforcements from Birdhamas to save Piggy Island and get their eggs back, Edgar reveals that he sent members of a legion, which consists of Boris Badenov, Dick Dastardly, Muttley, Bill Cipher, Plankton, Fat Cat, Lord Dominator, and Natasha Fatale, to stop the Flock from accomplishing their mission. After completely escaping and outsmarting them, who align with Baron Harmful, The Flock reach a peaceful island called Birdhamas, filled with other birds, which is the location of the legendary Golden Egg, an ancient egg-shaped artifact that allows its possessor to bend their own thoughts to their will. After interacting with the inhabitants and coming to the conclusion that they have to complete their journey due to being ‘angry heroes’, Bomb assures his flock that they won't give up as King Matthew, Nigel, Richard, Professor Mario, Louis, Doug, and Ross, whom were exiled from Piggy Island by Edgar, arrive and shows them what has happened to Piggy Island while they were gone, and Professor Mario Pigsworth upgrades their boat. They make camp in the island, after the inhabitants of Bird Town accept that they'll help, much to Bomb's delight.

After going back to Piggy Island, they only find the Pig Palace has been destroyed by Baron Harmful. The Flock now realize that the mastermind behind Baron Harmful's arrival is also their archenemy, Edgar Baconhooves. Bomb is initially shocked by this, but steels himself and tells Edgar that he made a massive mistake causing Baron Harmful's arrival. Edgar, however, cunningly retorts back and mockingly tells him that he finally had his revenge on the Flock and the pigs and he will eat the eggs once and for all. Furious at what he did recently, Bomb and his flock are ready to beat Edgar and his goons, but Baron Harmful stops them catching them in a net and throws the Flock (sans Poppy, Willow, Bounci, Dahlia, Eugene, Luca, and Gale) into a portal. The Flock flies over half of the real world all the way to the Statue of Liberty and they end up crashing into it. Bomb and his friends, now animated in stylized CGI, find themselves at Los Angeles, as they have to go find shelter in a hotel. After a while, Bomb, Red, Jay, Matilda, Hal, Terence, Bubbles, and Chuck realized that Baron Harmful is in fact Judge Doom reincarnated, plotting to manipulate Chef Pig to wipe Toontown out with the explosive sapphire orbs. While looking for a place to sit, a discouraged Hal begins to lose hope and becomes depressed. After seeing him down on the dumps, Scarlett Johansson motivates Hal to never lose faith on his friends and never give up, restoring his confidence.

Seeing his friends enter a heated argument, Hal manages to successfully stop this before it gets too heated with a rousing speech. The Flock resolve their differences, while they wonder how they get back to Piggy Island. Hal manages to lead the flock into another multidimensional portal, Frost attempts to recruit former Californian private investigator Eddie Valiant, but accidentally locates Eddie Murphy instead. Fortunately, he brings Sofia Vergara along as the latter offers them a slingshot. They managed to launch the Flock back to Piggy Island.

The Flock reverted back to their traditional forms and return to Piggy Island to save the captive pigs and Toons and attack and defeat Baron Harmful by firing themselves over his colossal ship using their giant slingshot. Hal sees that the Flock has been cornered by Edgar and his army, whom are ready to cook the eggs, and is very furious about it. Hal launches himself via slingshot with no mercy, lets out a massive bull roar, and attacks Edgar and his mooks to save his flock and the eggs. Edgar begins to have a bit of an existential crisis. However, Baron Harmful reveals his plot to use his sapphire orbs which are loaded with dip, which is revealed to be newly revived by Edgar, to destroy not only Piggy Island, but Toontown as well, so that both will be extinct from the Tooniverse forever, much to Edgar's shock and dismay. Initially uncaring after an argument for his disagreement, Baron Harmful becomes infuriated at Edgar for not knowing about Judge Doom's full name, to the point where he accidentally blurts out and reveals that he IS Judge Doom reincarnated via worldwide satellite transmission to Toontown secretly by Red, much to the fear and shock everyone (sans the Flock), calling him a "sniveling treacherous little swine" and throws him out of his ship. The Flock save Edgar from falling and reunites with the Eggs. Edgar apologizes to the Flock, saying that he only now understands why keeping the Great Egg War going is a bad idea. Edgar and The Flock work together to beat Baron Harmful, but to no avail. Baron Harmful traps the Flock and prepares to destroy them.

Just when all hope seems lost, Bugs Bunny calls in Winnie and her flock, the pigs, and every single Toon, including the Looney Tunes, Garfield, the Mystery Inc. gang, Woody Woodpecker, The Nicktoons, Finn and Jake, Steven Universe, Mordecai and Rigby, The Tiny Toons, the Warner Siblings, and Rocky and Bullwinkle to arrive and help the Flock. An all-out war broke between Baron Harmful's army and the Flock. All of the birds, toons, and pigs fend off Baron Harmful's army while the Flock keeping the eggs away from them, driving all but Harmful away, and battle against Baron Harmful, using assorted Toon props against him, all the while proving more than a match for him. The Flock separate themselves to distract and attack him. There, they each taunt Baron Harmful about his obsession of freeways and sadistic genocide of Toons, causing an incensed Baron Harmful to call in his minions, until Terence is able to run Harmful over like a steamroller before he gets to do it. He does not kill him however. Instead, he flattens him like a pancake. A flattened Baron Harmful takes the golden egg and fuses himself with it, causing him to transform into a very dangerous psychopathic toon/crow/dragon-like hybrid kaiju that can shape-shift into a giant amalgamation of various toons and begins to attack the Flock, being more powerful than before, with Don Bacon and Patsy unsuccessfully battling them as Chuck drops a ton of bricks on them.

Baron Harmful steals the eggs and tries to eat them, but his teeth cracked, and then Hal reveals that he and the Blues has painted three egg-shaped rocks white to make them look like eggs while they were battling him. Furious, Baron Harmful manages to spitefully hurl a box of TNT at the flock, but Hal and Bomb throw a can of sardines in his way before he throws the TNT, summoning the Mighty Eagle, destroying his ship and literally punches the Golden Egg out of him. An vengeful and deranged Baron Harmful, back in his normal form, yells at the Flock that he will return to try to wipe Piggy Island and Toontown off the face of the Tooniverse, while strangling Bomb's fuse, revealing his intention of returning with more crows. In the middle of his rant, however, Chuck drops an anvil on Baron Harmful, which knocks him out. King Smoothcheeks and the pigs stand before the defeated crow and Bomb, Red, Hal, and Chuck stuff a shrunken dip-filled sapphire bomb down Baron Harmful's throat, grab him by the crest and spin him around before tossing him way up high in the sky, before the bomb explodes inside him, which results in him to be violently electrocuted and then melting into nothingness, disintegrating him for good, while Don Bacon and Patsy are arrested for their crimes against Piggy Island. The Flock and Edgar rebuild Pig City with the help of the Toons, but when the Flock and Edgar see an anguished Leonard mourning the loss of the Pig Palace, Bomb and the others feel bad for him and join him. As they mourn, Edgar apologizes for his actions towards the Flock and the Pigs over all these, as his recent actions caused the destruction of the Pig Palace they had so many memories with. However, Bomb, Red, and Chuck refuse to let the memories fade away, and convince the others they can rebuild the castle if they all work together to which he approves while hearby bequeathing the property to Piggy Castle to Matthew.

A week later, the All-Toon Companionship Festival resumes, as Hal finally gets the recognition he deserves and is hailed as a hero along with the Flock in gratitude when Bomb gives out a speech about how Hal is not only the brains of their team, but also in fact the heart and moral center of the Flock. While being praised by the Pigs and the toons, The Flock even forgive Edgar when they sees him feeling regretful for the chaos he caused, and he offers them a makeshift sun visor for each egg. Edgar remarks that betraying his kind was the dumbest thing he's ever done. The Flock have a conversation with Mighty Eagle and are inspired to move forward, upgrading their slingshot and resuming their egg-guarding duties as they celebrate the Great Egg War's end, but have to be on even more high alert. The Flock guard and protect the eggs together and are now welcomed by the Toons, who now begin to acclimate themselves with the rest of the birds and pigs (even the old inhabitants of Aviantopia move in to Piggy Island) in various activities for life, as Bomb happily shows a sign reading "Welcoming change, ain't it?".

When the film ends, Silver insists on watching it again. Chuck tells her that they'll watch it again tomorrow until The Pigs, Lucy and Patrick (Chuck's mother and father), Winnie, Winnie's entire flock, and the rest of the toons want to watch the movie again as well, following an epilogue narrated by the Pink Panther detailing a fate and whereabouts of the toons if the film was critical and finacial success. A mid-credits scene shows The Flock welcomes Winnie and her gang to Piggy Island.

In a post-credits scene, The Flock being cheered by millions of Toons, due to their movie being a success, much to 2013 Teen Titans’ dismay, wanting a movie of their own.

Development
Following the success of Angry Birds X, Rovio Animation and Cartoon Network Studios announced that they would make a movie adaptation based on Angry Birds X in December 11, 2014, after the critical success of .

Originally, Warner Bros. Pictures, Cartoon Network, and Rovio were thinking about making it a live action/CGI hybrid a la Alvin and the Chipmunks and the Smurfs directed by Raja Gosnell and produced by David Kellogg.

On January 30, 2015, plans shifted from a live-action/CGI hybrid film to a fully traditionally animated film, that would be "in the same vein as the source material", with the help of a one-time collaboration of Warner Animation Group and Sony Pictures Animation.

In August 1, 2015, Warner Bros. watched, , and , and decided to make it a fully 2D-animated movie with live action sequences mixed in. Filming began on March 1, 2016 and wrapped on August 3, 2016. Rubber mannequins of the Flock would portray the animated characters during rehearsals to teach the actors where to look when acting with "open air and imaginative cartoon characters".

Joe Dante convinced Disney, MGM, Paramount, Universal, Twentieth Century Fox, King Features Syndicate, Mattel, Bagdasarian Productions, Nintendo, Nickelodeon, Sega, Turner Entertainment, Paws Inc., VOOZ Character System, Peanuts Worldwide LLC, Film Roman, Allspark Animation, and Xilam to lend their characters to appear in the film, the same way Spielberg convinced Warner Bros. and the various other companies to lend their characters to appear in.

In September 2016, it was announced that Heitor Pereira and Christopher Lennertz are both composing the score for the film together, which will include themes from the Angry Birds games, in collaboration with series composer Ari Pulkkinen.

Animation and visual effects
The 2D hand-drawn animated sequences for Angry Birds X: The Fine Feathered Movie were done by either Top Draw Animation, Mercury Filmworks, Yowza! Animation, Passion Pictures, Rough Draft Studios, Tonic DNA, Sunmin Image Pictures, Boulder Media, and TMS Entertainment, using digital-ink-and-paint, the animation is directed by and  who also supervised the 2-D animation when it blends with the live action environment. Panty and Stocking from were done by Gainax, who animated them for the series.

The characters from The Adventures of Jimmy Neutron: Boy Genius and Back at the Barnyard were done by Omation Animation Studio, who animated for the latter.

According to art director Andrea Torrejon, they still wanted to keep to the look and feel of the television show, in which the larger budget enabled them to add "simple yet impactful changes" to the designs for the big screen, such as depth and shadows for their eyes, beaks, and crests and the impression of flowing fluffy feathers on their plumage.

The film's visual effects were provided by Industrial Light & Magic, Luma, Jim Henson's Creature Shop, and Cinesite. Much of the visual effects were provided by the same team behind Teenage Mutant Ninja Turtles, Who Framed Roger Rabbit, and Space Jam. Numerous animators who worked on films like Who Framed Roger Rabbit and The Angry Birds Movie have also been involved with the animation of the movie, while additional 2D Animation was provided by Toon City, Atomic Cartoons, Karrot Animation, and Copenhagen Bombay Productions Aps, who previously worked with Rovio on Angry Birds Toons.

The film also used computer-generated imagery (CGI) for the Flock, when they're in the real world, which was handled by Blue Sky Studios in Greenwich, Connecticut, who hired 3D animators with a passion for 2D animation for the project. Following the strategy of basing the animation off a stylized 3D/CGI VFX modeling medium through a 2D finish by creating innovative rigging, animation techniques used to create 2D animation, and custom tools such as lighting and rendering, resulting in the film's 3D/CGI animation embracing the look and feel of 2D animation. Inspiration for the visual CGI style of the Flock came from Blue Sky's The Peanuts Movie (2018) and Sony Pictures Animation's Hotel Transylvania (2012), to make the Flock look more cartoony while staying faithful to the original designs. Sony Pictures Imageworks is provided for the live-action objects the Flock had to interact with in the film.

Unlike other live-action/animated hybrids after Who Framed Roger Rabbit, Space Jam, and Looney Tunes: Back in Action, the animation of the characters followed the same steps as Roger Rabbit and Space Jam:
 * 1) The animators and lay-out artists were given black and white printouts of the live action scenes, placed their animation paper on top of them and drew the animated characters in relationship to the live action footage.
 * 2) After rough animation was complete, it would run through the normal process of traditional animation until the cels were shot on the rostrum camera with no background.
 * 3) The animated footage was then sent to Industrial Light & Magic for compositing, where technicians would animate three lighting layers (shadows, highlights and tone mattes) separately, in order to make the cartoon characters look three-dimensional and give the illusion of the characters being affected by the lighting on set.
 * 4) Finally, the lighting effects were optically composited on to the cartoon characters, who were, in turn, composited into the live-action footage.

Deleted scenes/characters

 * In the early drafts, SpongeBob was a main character. Most of his scenes were removed to make room for other scenes.
 * At the movies, the movie theater usher, which is actually Bugs Bunny filling in for the real movie theater usher, lets every toon into see the Flock's movie, but doesn't let the Teen Titans, from Teen Titans Go!, in, because of what they've done in The Return of Slade, The True Meaning of Christmas, Money Grandma, etc, so Moxy reminds them that Cartoon Network hates them and told every movie theater in the world that if they see their faces trying to come see their movie, they kick them out.

Music
The film's score is composed by Heitor Pereira and Christopher Lennertz, Lennertz and Pereira are working closely with longtime Angry Birds composer Ari Pulkkinen to incorporate themes from the games within the film's score. but some of the tracks used are taken from The Angry Birds Movie, also composed by Pereira, and Who Framed Roger Rabbit, composed by Alan Silvestri. The song also includes some interludes from "Space Jam".

Home media
Angry Birds X: The Fine Feathered Movie was released on digital HD on June 3, 2018, and on Blu-ray and DVD on June 12, 2018, from Warner Bros. Home Entertainment, with #VanityInsanity, a short film based on Lauren Faust's forthcoming DC Super Hero Girls television series, five Angry Birds shorts, two Roger Rabbit shorts, Tummy Trouble and Trail Mix-Up, and four Looney Tunes shorts included.

Reception
Review aggregator Rotten Tomatoes reports that 95% of critics gave the film positive reviews, based on 132 reviews. The site's consensus reads, "With its strong characters and eye-popping cartoony animation, Angry Birds X: The Fine-Feathered Movie is both amazingly action-packed and heartwarming, while being surreally goofy and entertaining for both animation fans and movie fans."

Cancelled sequel
In July 12, 2019, a sequel was reported in development for a summer 2020 release. One of the directors, Genndy Tartakovsky, reported that the sequel "would be made on the same budget as Who Framed Roger Rabbit. The film was cancelled because the writers could not decide on which story would they work on.

Cultural references

 * The scene where Ralph T. Guard trying to eject the Flock out of the Warner Bros. studio is similar to his portrayal in Tiny Toon Adventures where he guarded the Warner Bros. Studios, and was often at odds with the Tiny Toons, usually Plucky Duck.
 * Throughout the beginning is a giant middle finger to live-action adaptations of cartoons from every toon protesting Warner Bros. to make the Flock’s movie 2-D animated, to Yogi Bear and Scooby criticizing their live action movies, Shaggy chastising Matthew Lillard's portrayal of him again (being a reference to Looney Tunes: Back in Action), Finn, Chowder, and Flapjack agreeing to never make a deal with Hollywood to make a live-action adaptation, and Yakko telling Wakko and Dot that the Flock have got the "live-action treatment".
 * When The Flock came across Freddie Prinze Jr., Sarah Michelle Gellar, Linda Cardellini, and Matthew Lillard and Jay, Jake, and Jim asked if they had any regrets. They replied "Scooby-Doo, maybe.", possibly a reference to Zombieland, where Bill Murray actually regretted starring in Garfield.
 * One scene has Fifi La Fume interacting with Gumball Watterson, Muscle Man, and Peridot, with Muscle Man roasting Fifi La Fume for hiding in the food dish cover on a serving cart by saying his traditional "My Mom" jokes, making Fifi a little annoyed and embarrassed, being a reference to Tiny Toon Adventures: How I Spent My Vacation.
 * The scene where Blossom, Bubbles, and Buttercup telling Thaddeus Plotz to make the Flock’s movie fully animated, with Bubbles pleading Plotz to not let it bomb at the box office is a nod to how The Powerpuff Girls Movie bombed at the box office
 * The scene where The Flock spot 7-Eleven is a nod to the Walmart scene in Looney Tunes: Back In Action.
 * When Bugs Bunny mocks Thaddeus Plotz, it’s a reference to the Looney Tunes short, "Wabbit Twouble", when Bugs Bunny mocked Elmer Fudd.
 * When the cartoon characters and the Flock see Elmyra Duff, they either groan or kick her out to the curb which is a reference to how the fans of Tiny Toon Adventures hate Elmyra Duff.

Trivia

 * This is the sixth Cartoon Network theatrical film, the first being the Powerpuff Girls Movie, the second being The Chowder Movie: The 10001st Thrice Cream Flavor, the third being Flapjack: The Grand Misadventure to Candied Island, the fourth being Regular Show: The Movie, and the fifth being Shantae: Half-Genie Hero.
 * This is the fourth Warner Animation Group film to be in traditional 2D animation.
 * The film will mark Warner Animation Group's first live-action/animated hybrid film, followed by (2021) and  (2021).
 * This marks Roger Rabbit, Jessica Rabbit, and Baby Herman's first animated appearance since the 1993 short, Trail Mix-Up. Roger will appear again in the upcoming live action/animated Chip 'n Dale Rescue Rangers movie.
 * Originally, Baron Harmful was gonna be a vulture and Judge Doom's pet named Constantine Voltaire, a reference to the deleted character to Who Framed Roger Rabbit, that declares revenge on all toons, especially the Angry Birds, for letting Eddie Valiant defeat his deceased owner, but that idea was dropped in the interest of making him a more interesting and threatening villain by turning him into a crow reincarnation of Judge Doom.
 * When Baron Harmful transforms into a chimera-like toon monster, he resembles a combination of animated characters:
 * Head: Mixture of Golly Gopher from Re-Animated and Out of Jimmy's Head, Kneesocks Daemon from Panty and Stocking with Garterbelt, the Cheshire Cat from Disney's 1951 version of Alice in Wonderland.
 * Eyes and Hair: Judge Doom's true form from Who Framed Roger Rabbit.
 * Nose: Stimpy from The Ren and Stimpy Show.
 * Right Leg: Cyborg from Teen Titans Go!
 * Left Leg: Lynn Loud from the Loud House.
 * Left Arm: Bill Cipher from Gravity Falls.
 * Shoulders: Mixture of Aku from Samurai Jack and Lord Dominator from Wander Over Yonder
 * Right Arm: Dark Danny from Danny Phantom.
 * Glasses: Mixture of Mandark from Dexter's Laboratory and Denzel Crocker from the Fairly OddParents.
 * Torso: Fat Cat from Chip 'n Dale Rescue Rangers
 * Tail: Pepe Le Pew from Looney Tunes
 * Voice: Glowface from the X's, The Joker from Batman: The Animated Series, and Godzilla
 * Laugh: Ren Höek from The Ren and Stimpy Show.
 * Given that the movie's world is pretty identical in concept to the world of Who Framed Roger Rabbit (as in, animated Toons of all kinds existing alongside real humans in a live-action world), along with Roger's aforementioned cameo, this movie is actually in-continuity with that movie, taking place in the same world in 2018 (30 years later), making this movie a spiritual successor to that movie, in a "shared universe" sense.
 * This is the only Warner Animation Group film to feature Disney characters.
 * Despite Sony Pictures Animation having involvement in the film, Columbia Pictures or Sony Pictures Releasing didn’t distribute it.
 * The movie is considered by diehard Angry Birds fans to be an homage to Poached Eggs and Mighty Hoax.
 * This is the only Warner Animation Group film to have a prologue appear before the opening logos.
 * This is the first animated film produced by Amblin Entertainment, since the closure of Amblimation.
 * Despite being produced by Cartoon Network (in association with Rovio Animation and Steven Spielberg's Amblin Entertainment), Angry Birds X: The Fine-Feathered Movie also marked the second time that characters from several animation studios appeared in one film, the first being.
 * The Teen Titans are depicted and portrayed as their 2003 animated counterparts.
 * Several voice actors make cameos as the voice of the character(s) they have played before. These are Candi Milo (Dexter, Sweetie Pie, Coco), and Charlie Adler (Buster Bunny, Candy Hector Caramella, I.R. Baboon, Cow, Chicken, and The Red Guy). But most noticeable is Mindy Cohn as Velma Dinkley. Mindy did Velma's voice from 2002 - 2015.
 * While the movie is going to be a Roger Rabbit-esque film with the 2D animation feeling more prominent than Who Framed Roger Rabbit, the animation treatment, when the Flock gets transported to the real world, will be cel-shaded CGI animation that will have the look and feel of 2D animation, promised to be in the vein of animated movies based on cartoons, while being more fluid, in both the character designs, and the overall character animation.
 * This is the only Angry Birds movie to be 2D animated.
 * This is the only time Calamity Coyote speaks.
 * Charlie Adler reprises his role as Buster Bunny.
