Film Summary
The film is set three years in the future after the events of  Come Along with Me , where Finn (now 20 years old) and his friends are just about ready to enjoy the rest of their lives while the Kingdom of Ooo is finally at peace. When suddenly, a new foe named Lord Grim, the son of the Lich, kidnaps Princess Bubblegum and takes over the Kingdom of Ooo during the big celebration of the GOLB being defeated by Betty because he wants revenge on Finn about his father's defeat, so now, the lands of Ooo and Aaa, the farmworld versions of the heroes, the Guardians of Sunshine video game version of Finn and Jake and the minecraft versions of the heroes collide in the multiverse, and they unite to stand up and fight against Lord Grim, his monsters, the Four Demon Kings, his sidekick Me-Mow and the reborned Lich and save the Kingdom of Ooo.

Plot
Three years after the events of  Come Along with Me , the Kingdom of Ooo was now at peace. In the beginning, Finn has turned 20 years old and now, he and Jake live with his parents in their rebuilt treehouse that got destroyed by a horrendous creature. And for Princess Bubblegum and Marceline, they' re still hanging out with the ladies. So, basically, everything is back to normal after Betty merged with the GOLB and departed from Ooo, saving Simon. The next day, Finn and Jake go out for a walk and they meet the future adventurers, Shermy and Beth. After they meet each other, Shermy and Beth told Finn and Jake that they are their biggest fans. Then, Finn and Jake meet up with the princesses and Marceline and they all start to relax outside on the grass. While they relax, the Kingdom of Ooo celebrate the day Betty saved Ooo from the GOLB.

Finn thinks his years of saving Ooo is over because it is finally at peace. When suddenly, Finn and his friends notice the sky becoming dark and gloomy. Then, a new villain named Lord Grim arrives from nowhere. During arrival, everyone in Ooo gathers as a crowd to meet this unknown stranger. Grim then asks for a way to open a wormhole, but then, everyone realizes he's trouble. So, Finn and his friends fight him with every weapon they got. But nothing worked because Lord Grim was more powerful than him and he used his power to make Finn hand over The Enchiridion. However, his action accidentally opens up a wormhole, which Princess Bubblegum kicks Grim, but then, Lord Grim reveals that he actually wants revenge on Finn about his father's defeat by kidnapping Princess Bubblegum and orders the monsters, including his sidekick Me-Mow, to attack them, but the heroes escape.

The next morning, as Finn and the others come with a plan to save Princess Bubblegum and the Kingdom of Ooo, Jake and Marceline decide to visit Gumbaldia to ask for the kingdom's help. They meet with Aunt Lolly who now rules the candy city, Gumbaldia. While Finn went for a walk to come up with an idea, he meets a failed actress Brenda, and immediately falls for her, something that he thought was impossible as he had never already loved before.

With no other option, they tried to give up, at least until Finn shows up with Brenda, the magic woman. Grim learns of Finn's survival and forms an alliance with numerous past villains from throughout the series who have been reborned, including some new villains, in preparation for the final battle. Before the war, Lord Grim sees that Finn has come back with his friends, along with The Enchiridion. After arrival, Brenda greedily betrays Finn by taking The Enchiridion from him and giving it to Lord Grim and then, Grim destroys the Candy Kingdom, and creates a new kingdom with an army of undead warriors, the Four Demon Kings, brings his dad, the Lich, back to life, along with the previous villains from the series, who are reborned, and also kidnaps Prince Gumball and banishes Finn, Jake and his friends out of Ooo.

While lost in the forest as began to snow, Finn is attacked by the wolves, but his friends save him and take him to the Igloo. While taking him to the Igloo, they met Fionna, who is banished out of Aaa, along with Cake, and Finn's friend, Simon, immediately falls in love. Meanwhile, as Candy Kingdom is now under Grim's control, Lord Grim approached the mystery villain to collect revenge on Princess Bubblegum. Me-Mow and Brenda arrived their master and said what Princess Bubblegum is believed to be Finn's weakness and Finn not renounces be a hero yet. But Lord Grim is never to worry, but he said soon Princess Bubblegum will be Grim's greatest weapon, which will lure Finn back in Ooo to surrender.

After challenging several dangers, as the evil witch, the abominable snowmen and the Eagle, Finn is kidnapped by evil versions of Flying Lettuce Brothers, Gareth, and Tiffany, who create a evil-like version of Jake to finish him. After the fight, Jake takes down the evil versions of his old gang and saves Finn from the certain death. Now, the heroes rush back to Candy Kingdom to stop Lord Grim from taking over. Back at Candy Kingdom, Finn see Princess Bubblegum held captive, who is also used as Grim's greatest weapon. Lord Grim makes Finn choose what to do: Either surrender or see Princess Bubblegum be trapped in a prison bubble? So, Finn dropped his weapon and surrendered, much to Princess Bubblegum's discomfort. Lord Grim finally creates a evil plan to take over Candy Kingdom full of undead creatures and monsters, while also trapping Princess Bubblegum in a prison bubble, even though Finn surrendered, and eventually betraying Brenda because he used her. But then suddenly, the entire multiverse appears, which includes: the farmworld heroes, the land of Aaa, the Guardians of Sunshine video game version of Finn and Jake and the minecraft versions of the heroes. And Flying Lettuce Brothers, Gareth, and Tiffany join the battle to fight against Lord Grim and his army, but Jake asks why they're the good guys because he thought they were evil, but Tiffany explained the whole thing by telling Jake that after he saved Finn and ran back to the Candy Kingdom, he and the others saw the evil versions of themselves and attacked them, which gave them enough time to summon the multiverse, which explains why the entire army of the multiverse appeared to help the Candy Kingdom battle against Lord Grim and the chaos creature.

As the chaos creature, four demon kings and undead warriors attack, Finn sends Princess Bubblegum's Gumball Guardians and the multiverse to fight them, while Lolly assists with Gumbald's giant robot, and Brenda tries to redeem herself by assisting with using her magic powers. The creature overpowers everyone and seemingly crushes Gumball, enraging Marceline and Marshall Lee, who assume more powerful forms and kill it. Gumball revives, and he hugged Marceline and Marshall Lee because they saved his life. The chaos creature then forms again and heads towards the treehouse. Jake witnesses the creature destroying his and Finn's tree house, and becomes despondent. BMO finds him and sings a comforting lullaby to him. The song's harmony negatively affects the chaos creatures, since the Lich's power is derived from chaos itself. Finn encourages everyone else to sing the song again because it worked on the four legged monster in "Come Along With Me", further weakening Grim's monsters, along with Bad Jake and the other villains that were brought back to life by Lord Grim.

After the battle, Finn, Brenda, and Simon try to break Princess Bubblegum free from the prison bubble, and uses The Enchiridion to summon a portal that sucks Lord Grim, his army and Me-Mow into it. With enemies gone, Candy Kingdom goes back to normal and Brenda has redeemed herself. Finn was proclaimed as a hero and Brenda restores the love relationship with Finn, apologizing him for her behavior and for using him just like Lord Grim used her. As Finn and Brenda's love relationship is restored, Finn leaves his friends and family and the Tree Fort, just before he grows up, with his girlfriend, Brenda.

BMO concludes the story, saying everyone else "lived their lives", and bids farewell to the audience.

During the credits, a montage with the song "Come Along with Me" is shown, revealing the future of the characters, including the adult Finn breaks the fourth wall, marries Brenda and have two kids. Shermy and Beth were thinking of starting a new adventure of their own, promoting Shermy to say, "What time is it, Beth?" and they both said in unison, "Adventure Time".

Announcement
On February 27, 2015, it was announced that there will be an Adventure Time animated feature being developed at Warner Bros. and Frederator Studios and its release date of August 3, 2018 was also announced, with the show's cast reprising their roles. Cartoon Network Studios will also be involved with production. Mike Mitchell, who directed The SpongeBob Movie: Sponge Out of Water, is directing the film, and Kelly Crews is going to be producing the film, alongside Chris McKay (an executive producer for The Lego Movie and director for The Lego Batman Movie as well as the genius behind Robot Chicken). In October 2016, it was announced that Pendleton Ward, the original show's creator, will write and produce the film and will also be the executive producer with Adam Muto, Fred Seibert, Brian A. Miller, Jennifer Pelphrey, Curtis Lelash and Rob Sorcher. On May 8, 2016, it was announced that Chris Ayres, Kathleen Barr and Whoopi Goldberg had joined the cast. The film marks the ninth time a theatrical Cartoon Network film is produced by Warner Bros. Animation, instead of Warner Animation Group since the group's formation in 2013.

Development
Warner Bros. Animation had already begun the process of starting development of movies with budgets of around $100 million. The intellectual property for these films was meant to be supplied by Warner Bros. Animation, Hanna-Barbera (Warner Bros. Animation's in-name only division), Cartoon Network and Turner Entertainment (also both Time-Warner divisions) among others and included The Flintstones, The Jetsons, Scooby-Doo, Samurai Jack, Adventure Time, Cow and Chicken, and more, of course, Codename: Kids Next Door. Cartoon Network had been approaching the original crew from the television series to make a high-profile, animated theatrical feature-length film adaptation and had long wanted to partner with Warner Bros. Pictures to release an Adventure Time film given the network's extraordinary legacy in the world of animation, including some of the most enduring characters on cable television history.

Creator Pendleton Ward agreed to make a feature film version of the show with the promise it would be the first of a planned trilogy. During development stages of the film, he and his producer Kelly Crews and executive producers Adam Muto and Fred Seibert intended to revisit some of the greatest films of the time, with Scarface and The Dark Knight having the core inspirations for the film.

Animation
The feature animation was handled by Rough Draft Studios in Glendale, California and Seoul, South Korea. The crew used the same processes from the original television series in the making of the film, most notably the 'skroutlines', which was a seamless blend of a more traditional screenplay with a more simple outline which resembled strong short stories and gave the storyboard artists such as Kurt R. Anderson, Armen Mirzaian and Tom Herpich all the creative and aesthetic freedom neccessary. Ward and Sugar themselves provided the film's animatics.

Fellow storyboard artists Emily Partridge, C.H. Greenblatt and David C. Smith, and animation veterans Frans Vischer, Michael Gendi and Scott Mansz also provided the film's storyboards. Kelly Baigent helped on the character designs and special effects work on the film. Another animation veteran James Baxter also worked with Pendleton Ward on the character designs of the film.

The bulk of the animation work was done on Wacom Cintiq tablets, which allowed drawings to be done directly on screen to facilitate production using programs Toonz, DigiCel FlipBook and Toon Boom Studio. Pencilled key animation sequences would be digitally inked-and-painted, enhanced and composited into backgrounds using Toon Boom Harmony. Additional pre-production work was done at Cartoon Network Studios in Burbank, California where the series' pilot episode was produced. Animation was done at Rough Draft's facilities on both Glendale and Seoul, with clean-up work done at the main Glendale studio. Computer animation was done at Jam Filled Entertainment.

Sound and music
Casey James Basichis and Tim Kiefer composed the soundtrack for the film with Pendleton Ward and Ashley Eriksson serving as the soundtrack producers. In addition to using the original series' music work on the film, they also composed themes for each Adventure Time operative. Finn and Jake's adventure score was the major focus and they also composed themes for Princess Bubblegum, Marceline, Lumpy Space Princess, Simon Petrikov, Gunter, BMO and Lady Rainicorn, and Lord Grim. The music score was recorded and mixed at Warner Bros. Eastwood Scoring Stage in Burbank. The score is orchestrated and conducted by Thomas Newman.

The sound design work was done at Hacienda Post in Burbank, California and Cartoon Network Studios in Burbank, California.

Rating
Adventure Time: The Kingdom of Ooo is Rated PG for Parental Guidance.

Video game
A video game featuring a plot set directly after the film, titled The Kingdom of Ooo: The Game, was released in North America on August 3, 2018 (the same day as the release of the film) for the Nintendo 3DS, Xbox 360 and PlayStation Vita. The game is published by Activision. A mobile game, titled Adventure Time: Finn on the Run, was released on August 15, 2018 for iOS and Android. It is an endless running game based on the film, featuring several mini games.

Theatrical release
The film was theatrically released in movie theaters for the United States and Canada on August 3, 2018, by Warner Bros. Pictures, followed by a United Kingdom bow a week later, on the same year as Cartoon Network's previous film Mixels: The Movie, Mixing It Up A Notch. The film was presented in a 1.85:1 format, rather than Warner Animation Group's standard 2.39:1 format on its previous titles. It was scheduled to be released in Australia on September 27, 2018. The movie's theatrical release was preceded by Dream Night, a short film based on Cartoon Network's animated television series Apple & Onion.

Home media
The film was released on Digital on October 16, 2018 and Blu-Ray and DVD on November 6, 2018. It contains the deleted scenes, an Apple & Onion short film Dream Night, the 18-minute featurette, featuring interviews with most of the principal cast and crew, animatics, the deleted ending, the pilot episode, the audio commentary and a sneak peek of The Amazing World of Gumball: The Movie.

Box office
Adventure Time: The Kingdom of Ooo has grossed $59 million in the United States and Canada, and $86 million in other territories, for a total worldwide gross of $146 million, against a production budget of $50 million.

In the United States and Canada, Adventure Time: The Kingdom of Ooo was released alongside Christopher Robin, and was initially projected to gross around $126 million from 4,246 theaters in its opening weekend, with a chance to gross over $100 million.
