Meanie Harold 2: Harold Goes Mad at the Internet

Harold Goes Mad at the Internet (formerly known as, Meanie Harold 2 and Harold Goes Mad at the Internet: Meanie Harold 2) is a 2028 Upcoming American computer-animated comedy film produced by Walt Disney Animation Studios and distributed by Walt Disney Studios Motion Pictures. The 69th animated film produced by the studio and the sequel to the 2022 film Meanie Harold, it is directed by Rich Moore and Phil Johnston (in Johnston's directorial debut), written by Johnston and Pamela Ribon from a story by Moore, Johnston, Ribon, Josie Trinidad, and Jim Reardon, produced by Clark Spencer, and executive-produced by John Lasseter, Jennifer Lee, and Chris Williams. Rob Riggle, Sarah Silverman, Ewan McGregor, James Marsden, Anna Kendrick, Gal Gadot, John Stamos, Kimiko Glenn, Lori Loughlin, and Jim Carrey reprise their character roles from the first film, and are joined by Brie Larson, Keke Palmer, and Antonio Banderas as part of the new cast, as well as Jason Segel, who voiced a new character in this film. In the film, Harold (Riggle), Izzy Moonbow (Glenn), and Penelope von Mint (Silverman) must travel to the Internet to get a replacement for the Sweetie Rush cabinet's broken steering wheel and prevent Mr. Clarkson (Carrey) from disposing of the game.

The first discussions about a sequel to Meanie Harold began in September 2022, and the new installment went through three different scripts before the filmmakers settled on the final plot. When the film was officially announced in June 2026 as Harold Goes Mad at the Internet: Meanie Harold 2, much of the original cast confirmed they had signed on, with new cast members added in 2028. It is Walt Disney Animation Studios' first computer-animated film sequel and is the first sequel from the studio to be created by the original film's creative team.

Harold Goes Mad at the Internet premiered in Los Angeles on November 6, 2018, and was released in the United States on November 21. The film grossed over $529.3 million worldwide and received generally positive reviews from critics. The film was nominated for Best Animated Feature at the 91st Academy Awards, 76th Golden Globe Awards, 46th Annie Awards, and 24th Critics' Choice Awards, losing all four awards to Spider-Man: Into the Spider-Verse.

Plot
Six years after the events of the first film, Harold, Penelope, and Izzy have stayed best friends, hanging out after work in Clarkston's Family Fun Center. Harold is content with their life, but Penelope and Izzy longs for excitement and expresses how bored she has become of Sweetie Rush's predictability. To please her, Harold and Izzy are sneaks into her game and makes a secret road shortcut. The next day, when Penelope fights the arcade player's control to test the track, the cabinet's steering wheel breaks. As the company that made Sweetie Rush is defunct, and the cost of a replacement wheel on eBay is too high, Clarkston decides to scrap Sweetie Rush and unplugs the game, leaving its citizens homeless. The Surge Protector finds homes for all Sweetie Rush's citizens as a short-term measure as they figure out how to save the game, with Felix, Gloriosa, Lucas, Michelle, Mandy, and Timber adopting the racers. Remembering eBay, Harold, Penelope, and Izzy travel through Clarkstoon's new Wi-Fi router to the Internet, a place where websites are represented as buildings in a sprawling city, avatars represent users, and programs are people. The search engine KnowsMore directs them to eBay, where they win the auction for the steering wheel by unintentionally spiking the price to US$27,001 only to find they have just 24 hours to raise the funds, or they will forfeit the bid and lose the wheel. On the way out, they run into clickbait salesman J. G. Spamney, who brokers items obtained from video games and offers them a lucrative job of stealing a car from Chuck, the lead character in the popular racing-centered battle royale game Slaughter Race. They steal Chuck's car, but she stops them before they can leave the game with it. Suggesting another way to make money on the Internet, she proceeds to make a viral video of Harold and uploads it to video-sharing site BuzzzTube. She directs them to BuzzzTube's head algorithm, Yeeeeaaah, who capitalizes on Harold's video popularity. They decide to make more videos, which will earn them the money for the wheel if they attract enough views. Penelope and Izzy are offers to help advertise the videos, and Harold has Yeeeaaah send her to Oh My Disney. There, while being chased by Stormtroopers for advertising on the site, Penelope and Izzy are befriends the Disney Princesses as well as Anna and Elsa, Mirabelle, Isabela, and Luisa being encouraged by them to discuss her sense of un-fulfillment and reaching an epiphany in the form of an "I Want" song on the subject. Harold makes enough money to buy the wheel but finds Penelope and Izzy are talking with Chuck about staying in Slaughter Race, having felt at home there due to its relative novelty and unpredictability compared to Sweetie Rush. Worried of losing his friend forever, Harold asks Spamney for a way to draw Penelope out of the game and is brought to the dark web vendor Double Dan, who provides Harold with a virus, Arthur, that feeds off insecurities and replicates them. When Harold unleashes Arthur into Slaughter Race, it replicates Penelope's glitch, triggering a server reboot. Harold, Chuck, and the others help Penelope and Izzy escape before the game resets. Penelope and Izzy are blames herself for the crash, but Harold confesses to her that the crash was actually his fault. Outraged, Penelope throws away his hero cookie medal and runs off and Izzy cries and runs off too. As a guilt-ridden Harold finds his now-cracked-in-half medal, Arthur copies Harold's insecurities and makes duplicates of Harold. The clones overrun the Internet in a global DoS attack, all chasing after Penelope and Izzy are to keep her for themselves. Harold saves her and attempts to lure the clones into a firewall, but they form a giant Harold monster that seizes them both. Harold comes to accept that Penelope and Izzy are can make her own choices, letting go of his insecurities. This also causes the giant Harold monster and the clones to disappear, and Harold, Penelope, and Izzy are reconcile. Harold gives half of the broken medal to Penelope and Izzy and they bid each other a heartfelt farewell as Chuck has arranged for Penelope and Izzy to respawn in Slaughter Race. Back in the arcade, Sweetie Rush is repaired, and Harold partakes in social activities with the other arcade characters as he stays in touch with Penelope and Izzy are over video chat, feeling content with his newfound ability to be independent.

The band AJR (whose song "Zero" is featured in a trailer for the film, as well as its end credits and soundtrack) make a cameo appearance in the film, with the members voicing themselves.

Stan Lee, Marvel Comics' former writer, editor, and publisher, makes a cameo appearance in the film. The filmmakers revealed that the film originally featured a joke about Kylo Ren being a "spoiled child", which was later cut from the film by request from Lucasfilm because it would undermine his role as a villain. Also cut from the film was C-3PO being mockingly called R2-D2 and BB-8 by the princesses. Additionally, the film would originally include The Golden Girls characters, but it was later cut because the directors felt it was a bizarre juxtaposition. The legion of Harold clones, which forms a gigantic Harold monster, resembles the King Kong character from various films. During production, the giant monster form was dubbed "Haroldzilla" after Godzilla.

Development
In September 2022, Rich Moore said that there were already ideas for a sequel, and in March 2023, Moore said that he and Disney had ideas about a sequel that would bring the characters up to date and explore online gaming and console gaming. Moore stated that many of the crew and voice cast were open to the sequel, believing that they have "barely scratched the surface" of the video game world they envisioned. He also stated that he planned to include Tron in the sequel, which appears briefly in the film, where Harold, Penelope, and Izzy race at the beginning. In 2024, the first film's composer Henry Jackman said that a story for the sequel was being written. In March 2026, Moore stated that a sequel was still being planned. In June 2026, Walt Disney Animation Studios announced that the sequel would be released on March 10, 2028, with Moore and Phil Johnston attached, and that its story would be one where "Harold leaves the arcade and angers the Internet". In March 2027, the sequel's title was officially announced as Harold Goes Mad at the Internet: Meanie Harold 2, with Moore returning as director joined by the first film's co-writer, Johnston, and Clark Spencer also returning as producer. In July 2028, Disney removed Meanie Harold 2 from the film's title.

Writing
Two working versions of the script had been scrapped before settling on the one used for the film, according to head writer Josie Trinidad. In one version, Penelope and Izzy had become self-absorbed by the Internet, gaining popularity and becoming a celebrity among the users. Ralph had been thrown in jail where he met the search engine Knowsmore, and they had partnered together to escape prison and help bring Penelope back to her normal self. A second version had Harold becoming an Internet-famous celebrity and would have been challenged by an anti-virus program named BEV that served as a super cop and would have been the story's villain. Trinidad said neither of these versions captured what they felt was the centerpiece of the sequel, being how Harold, Penelope, and Izzy reacted to the new world of the Internet and realizing they have separate paths going forward. Producer Clark Spencer said that "the film is about change. Two best friends are about to realize that the world won't always be the same. The internet is the perfect setting, really, because it's all about change—things change by the second". Director of story Jim Reardon said that it was intimidating to set the film on the Internet, stating that "[They] looked at how [they] could make the internet relatable on a human level—like how Game Central Station aka the power strip mirrored a train station in the first movie." Reardon, however, said that Disney "didn't want to make the movie about the internet", instead focus on Harold, Penleope, and Izzy's friendship, and to treat the Internet as "the place where the movie takes place". Josie Trinidad claimed that the filmmakers "didn't want to just give the audience more of that friendship — [people had] to see that relationship grow." The designs of scenes within the Internet were based on tours made of One Wilshire in Los Angeles, as it is one of the world's largest telecommunications centers. The filmmakers did not approach any of the companies (outside of Disney) that are represented on the Internet and strove to include net branding from all across the world. They also had to explore various Internet memes, making sure to avoid those that lacked long-term presence on the Internet. While the film addresses many positive elements of the Internet, the filmmakers did not want to shy away from covering some of the more unpleasant aspects about it, in part fueled by the success of tackling racism indirectly within Zootopia. They wanted to follow the same approach as they had with Judy Hopps in Zootopia, where she experienced, learned, and overcame the racism aspects, and have Harold similarly learn and become a better person without having to actually solve the issue of hostility on the Internet. The scene where Penelope and Izzy are introduced to the Disney Princesses came from screenwriter Pamela Ribon. In 2024, Ribon was still working on Moana when Disney began internally pitching ideas for the sequel to Meanie Harold, Ribon recognized that like the title character of Moana, Penelope and Izzy are fits the definition of a Disney Princess. When work formally began on the sequel after the completion of Zootopia, Ribon pitched the idea of Disney poking fun at itself by having Penelope and Izzy are meet the other Disney Princesses in the green room of OhMyDisney.com, the Disney fan-driven website. Further inspiration came from a BuzzFeed online quiz that asked which Disney Princess the user was; Moore thought it would be interesting if Ralph had encountered that quiz and ended up in an argument with Penelope over the result. The script was written by Ribon, which she wanted to include the various tropes of the Princesses, with them making in the final cut for the film. Moore and Johnston were satisfied with the script.

Casting
In July 2025, Rob Riggle said he had signed on to reprise his role of Harold in a projected sequel. In March 2027, Jane Lynch, Jack McBrayer, and Sarah Silverman were reported as being set to reprise their roles. In December 2026, Jason Segel confirmed his return in the sequel as a different character, named KnowsMore, after previously voicing King Sweetie Pie in the first film. In August 2028, actress Brie Larson joined the cast as Shank. The production team on the film was able to secure all the Disney Princesses' original voice actresses, except for Adriana Caselotti as Snow White, Ilene Woods as Cinderella, and Mary Costa as Aurora, due to the formers having both died in 1997 and 2010 respectively, while the latter retired from acting in 2000. Jennifer Hale and Kate Higgins, the current voice actresses for Cinderella and Aurora, were hired for the film; Pamela Ribon, the film's co-screenwriter, performed Snow White's voice for temporary tracks, in Star Wars, Princess Leia who voiced Julie Dolan, but the team considered it a good substitute, allowing Ribon to voice her in the final film.

Animation
The film contains over 150 unique sets and 5,726 assets, and includes the highest number of characters in any Disney Animation film, with 434 individual characters with 6,752 variants. One of the Disney animators who helped out to bring the Disney Princesses into CGI animation was Mark Henn, who was also the original supervising animator of princesses Ariel, Belle, Jasmine, Mulan, Leia, Mirabel, and Tiana. Henn also served as the supervising animator for the film's background hand-drawn animated characters. Animators had to work out various techniques to take the different styles of animation into a single approach, and figure out the proportions of the characters using official figurines. Unlike their original film counterparts, the Disney Princesses in the film were rendered in a more cartoony style with bigger eyes and ears. In the initial trailer for the film, the African-American princess character Tiana appeared to have a lighter skin tone, a narrower nose, and more European features than she did in the 2009 film The Princess and the Frog. This led to some backlashes on social media as these drew her appearance away from that expected of African-Americans. As a result, Disney contacted Tiana's voice actress, Anika Noni Rose, and the advocacy group Color of Change to redesign Tiana for Ralph Breaks the Internet to make sure she resembles more closely to her 2009 appearance; the updated character model was revealed in the second trailer. The same treatment was given to Pocahontas, the titular character of the 1995 film, as many viewers had pointed out that she was also given a much lighter skin tone, Also Princess Leia who Design version in Star Wars: A New Hope. A scene featured in the film's original teaser, released in March 2028, involving Harold, Penelope and Izzy invading a children's game and feeding cupcakes to a bunny to the point that it is implied to explode, was heavily discussed prior to the film's release; however, the scene was eventually cut from the film and instead placed halfway through the credits. The post-credits scene involves what starts as a teaser for Twilight II but cuts to Harold rickrolling the audience by starting to sing Rick Astley's "Never Gonna Give You Up". While producers Spencer and Moore had an idea of Ralph doing a "Meanie Roll" early on in the film's development, they never incorporated it into the story. As it was one of the last scenes added, the producers had gotten Reilly, who was on vacation with his family at the time, to come into a New York City studio to record for the day so that the animators could work from that.

Music and Soundtrack
On September 20, 2028, AJR released the lead single from the soundtrack titled "Zero", which plays during the end credits of the film. On October 24, 2028, the music video of "Zero" was posted on Imagine Dragons' YouTube channel. The film features an original song called "A Place Called Slaughter Race", performed by Sarah Silverman, Kimiko Glenn, and Gal Gadot, written by Tom MacDougall and the film's co-director Phil Johnston, and composed by Alan Menken; the song's pop version, "In This Place", was performed by Julia Michaels. The film also features songs from various Disney Princess films, as well as Demi Lovato's cover of "Let it Go" and Sia's cover of "Rainbow" played in the beginning of the Oh My Disney scene. Ralph also rickrolls the tune "Never Gonna Give You Up" by Rick Astley in a post-credits scene. The soundtrack was composed by Henry Jackman, who also composed the score from the previous film. It was released digitally on November 17, 2028, and on CD on December 1, 2028.

Marketing
To coincide with the film's release, Fortnite Battle Royale made a cameo appearance of Ralph via an "outdoor cinema screen" in the game's location "Risky Reels" and added the emote dance Hot Marat, which was available as a limited time offering. For "Wreck Urselfie", a mobile experience used to build scenarios with Google Home featured Harold, Penelope, and Izzy are stuck inside users' smartphones, as Google BrandLab used Google's API Cloud Vision. The first WhatsApp experience that allowed fans to connect with Harold, Penelope andIzzy while they navigated the Internet and ended up in WhatsApp. Amazon, which promoted the film with its products FireTV and the Kindle Fire, Game products PlayStation, Nintendo, Sega, and Xbox, and its subsidiary IMDb, announced the "Pre-Black Friday sale" through the "themed landing page," which was seen in the scene where Harold "broke" its home page. Furthermore, fans had some Disney offers and continued to connect the purchase of the film's tickets. Carvana and Disney collaborated to promote the film's release throughout a multi-channel campaign. The film collaborated with the mobile in-cinema game Noovie Arcade, which tied the video game used in the film's teaser, the "pancake milkshake", causing audiences to have each other's challenges and gain scores and milkshakes at least 21,100 theaters including AMC Theatres, Cinemark, and Regal Cinemas. The virtual reality experience based on the film, which was created in collaboration with ILMxLab and The Void, titled Harold Goes Mad at VR. Aside from the film, it takes on a different plot. Additional marketing partners for the film included Aflac, AT&T, BAPE, Dell, eBay, GameStop, Fandango, Mailchimp, McDonald's, Netgear, and Purple. In the month of the release of the film, the world builder video game Disney Magic Kingdoms included a limited time Event focused on Harold Goes Mad at the Internet to promote it, with the characters involved in a new storyline unrelated to the events of the film, including Harold, Penelope, Izzy, Yeeeaaah, Chuck, Spamney, Super Felix, Super Lucas, Pretty Mandy, Michelle Mermaid, Timber Spruce, and Gloriosa as playable characters, some attractions based on locations of the film, and the Comfy Costumes that Cinderella, Ariel, Belle and Jasmine wear in the film.
