Sonic the Hedgehog 3 (film)

Sonic the Hedgehog 3 is a 2024 action-adventure comedy film based on the Sonic video game series. The third in the Sonic film series, it was directed by Jeff Fowler and written by Pat Casey, Josh Miller, and John Whittington. Jim Carrey, Ben Schwartz, Colleen O'Shaughnessey, James Marsden, Tika Sumpter, and Idris Elba reprise their roles, with Keanu Reeves joining the cast. In the film, Sonic, Tails and Knuckles face Shadow the Hedgehog, who allies with the mad scientists Ivo and Gerald Robotnik to pursue revenge against humanity.
Sonic the Hedgehog 3 was announced in February 2022 during ViacomCBS's investor event before the release of Sonic the Hedgehog 2 (2022). Due to the 2023 SAG-AFTRA strike, filming for animated characters began in July 2023 in Surrey, England, and filming with actors began that November in London. Production ended by March 2024. The plot draws elements from the video games Sonic Adventure 2 (2001) and Shadow the Hedgehog (2005). Reeves was cast as Shadow due to the parallels between his performance in the John Wick films and Fowler's vision for the character.
Sonic the Hedgehog 3 premiered at the Empire Leicester Square in London on December 10, 2024, and was released by Paramount Pictures in the United States on December 20. It received generally positive reviews, with critics praising Carrey and Reeves' performances, as well as the visuals and Fowler's direction. It was a box office success, grossing $491.1 million worldwide on a budget of $122 million, becoming the highest-grossing film in the franchise, the second-highest-grossing video game film of all time, and the tenth-highest-grossing film of 2024. A fourth film is due to be released on March 19, 2027.
In 1974, a meteorite containing the alien hedgehog Shadow crash-lands in Oklahoma and is seized by the U.S. military. Shadow's power is experimented on by Professor Gerald Robotnik at a Guardian Units of Nations (G.U.N.) research facility under the supervision of Captain Walters; Shadow also develops a close friendship with Maria, Gerald's granddaughter. One night, as Gerald, Maria, and Shadow try to escape the facility to prevent Shadow from being taken away, Maria is accidentally killed in an explosion. Walters shuts down the facility, imprisons Gerald, and places Shadow in suspended animation.
Fifty years later, in 2024, an unknown individual hacks into a G.U.N. prison facility's system off the coast of Japan and releases a vengeful Shadow. In Green Hills, Montana, Sonic celebrates the anniversary of his arrival on Earth with Tails, Knuckles, and their adoptive parents Tom and Maddie Wachowski. G.U.N. Director Rockwell arrives and recruits Sonic, Tails, and Knuckles (dubbed "Team Sonic") to help apprehend Shadow in Tokyo. However, he overpowers the three and escapes.
Team Sonic meets with the now-Commander Walters, who informs them about Shadow's past. Suddenly, Dr. Ivo Robotnik's drones attack and fatally wound Walters, who gives Sonic a keycard before he dies. They decide to find Shadow without G.U.N.'s help as Rockwell discovers the missing keycard and turns against them. Team Sonic encounters Ivo's assistant, Agent Stone, who denies involvement in the attack; they form an uneasy alliance with Ivo and track the stolen drones to the abandoned G.U.N. facility.
Ivo encounters Gerald, his estranged grandfather and the mastermind behind Shadow's escape and the stolen drones, as Shadow captures the others. Gerald explains that the keycard is one of two needed to activate the Eclipse Cannon, an orbiting laser space weapon he designed for G.U.N. capable of targeting and destroying any location on Earth. He claims that he plans to use it to destroy G.U.N.'s headquarters in London to avenge Maria's death, and Ivo agrees to join him. Shadow takes the keycard from Tails and activates a miniature black hole to destroy the base as he, the Robotniks, and Stone leave.
Team Sonic escapes using a ring portal and recruits Tom and Maddie to steal the second keycard from G.U.N.'s headquarters, contending with the Robotniks and Rockwell. Tom successfully obtains the keycard by disguising himself as Walters, but Shadow buys his disguise, gravely wounds him, and takes the key, allowing the Robotniks to launch the Eclipse Cannon. Enraged, Sonic abandons Tails and Knuckles, steals the Master Emerald, and becomes superpowered using the seven Chaos Emeralds contained within. Sonic confronts Shadow, who also absorbs the Chaos Emeralds' energy to become superpowered. Sonic eventually overpowers Shadow but relents upon realizing he was being consumed by revenge. Sonic tells Shadow about the loss of his guardian Longclaw and that their love for the people they have lost is more important than revenge. Having a change of heart, Shadow agrees to help stop the cannon.
Aboard the Eclipse Cannon, Gerald intends to destroy Earth to avenge Maria's death. A horrified Ivo attempts to abort the firing sequence, preferring to rule over humanity rather than destroy it, but Gerald destroys the command console. Tails and Knuckles arrive, and the three knock Gerald into the reactor core, killing him. Sonic and Shadow block the cannon's beam as Ivo, Tails, and Knuckles steer it away from Earth, accidentally slicing off part of the Moon. Sonic loses his superpowered form and consciousness while blocking the cannon's beam with Shadow and falls back to Earth. Tails and Knuckles save Sonic using a ring portal to Green Hills. When the cannon’s core begins to melt down, Ivo makes a final announcement acknowledging Stone as his only friend before he and Shadow sacrifice themselves to move it away from Earth before it explodes. Sonic reconciles with Tails and Knuckles while Tom recovers from his injuries.
During a race with Tails and Knuckles, Sonic accidentally ends up in New York and is ambushed by an army of Metal Sonic robots but is saved by Amy Rose. Elsewhere, Shadow has survived the cannon's destruction.
Sofia Pernas and Cristo Fernández respectively play Gabriella and the twin brothers Juan / Pablo in La Última Pasión, a telenovela Ivo watches.
In March 2020, James Marsden confirmed that he had signed on for multiple sequels to Sonic the Hedgehog (2020). In February 2022, Sega Sammy Group and Paramount Pictures had been developing a third film after Sonic the Hedgehog 2 (2022). It was formally announced during ViacomCBS's investor event. Produced by Original Film, Marza Animation Planet, and Blur Studio in association with Sega Sammy Group, Jeff Fowler returned as director while Neal H. Moritz, Toby Ascher, Toru Nakahara, and Hitoshi Okuno returned as producers. Haruki Satomi, Shuji Utsumi, Yukio Sugino, Fowler, Tommy Gormley, and Tim Miller served as executive producers. Pat Casey, Josh Miller, and John Whittington returned to write the screenplay, with the former two also being credited for the story. Paul Greenberg and Oren Uziel received off-screen additional literary material credit. In addition, a spin-off television series for Paramount+, Knuckles, was developed simultaneously with the film.
In April 2022, Jim Carrey—who portrays Dr. Ivo Robotnik in the films—announced that he was considering retiring from acting. With his possible retirement, Moritz and Ascher confirmed that his role as Robotnik would not be recast in any sequels if he followed through with his retirement plans. However, they remained hopeful that they could develop scripts good enough for him to continue the role. Carrey conceded, requiring that "the angels bring some sort of script that's written in gold ink that says to me that it's going to be really important for people to see" if he were to continue.
In February 2024, Carrey was confirmed to be reprising his role. Elaborating on his decision to sign on, he stated that "I came back to this universe because, first of all, I get to play a genius, which is a bit of a stretch. And, you know, it's just... I bought a lot of stuff and I need the money, frankly". Fowler made note of Carrey's comments about a script of gold, printing it out in 24-carat ink, which Fowler says cost about $100,000.
On April 15, 2024, it was reported that Keanu Reeves had joined the cast as the voice of Shadow. Reeves had previously been a popular fancast for the role. Fowler said there was an "obvious corollary" between Reeves's performance in the John Wick series and the "vibe we're trying to channel" for Shadow, and thus these films served as a "perfect, albeit unconventional, 'audition'" for the character. Fowler attested that even if John Wick had never been made, he believed Reeves's established history with dark and edgy characters would have led to them casting him anyway. Miller said that Reeves had been the voice they imagined for Shadow during the writing process, and brought him up when discussing casting with Fowler and Ascher; they said that this process contrasted with their writing for Knuckles in the prior film, as Elba was not a popular fancast for the character and their conception of the voice was more generic.
Additionally, Marsden, Ben Schwartz, Tika Sumpter, Colleen O'Shaughnessey, Idris Elba, Lee Majdoub, and Tom Butler were confirmed to reprise their roles from the previous films. Krysten Ritter, Alyla Browne, James Wolk, Sofia Pernas, Cristo Fernández, and Jorma Taccone were cast in undisclosed roles; Taccone was previously hired as an episode director for the Knuckles series. On February 16, Browne's role was revealed as Maria. Browne had previously been in George Miller's Three Thousand Years of Longing (2022) and Furiosa: A Mad Max Saga (2024) films, and Fowler said the team "inherited his great casting" of the actress. Fernández played the roles of Pablo and Juan in the in-universe telenovela La Última Pasión, alongside Pernas.
Sonic the Hedgehog 3 draws inspiration from the video games Sonic Adventure 2 (2001) and Shadow the Hedgehog (2005). Miller said that adapting Sonic Adventure 2 meant that a main question was "how dark can it get" while remaining PG-rated, and Casey said that a main challenge was how to tie Shadow's backstory together with Sonic's story, which he said was achieved by looking at the thematic parallels of the significance of family between the two. Among the elements from Sonic Adventure 2 incorporated were the fairy-like creatures the Chao. In the film, they are part of a Chao Gardens-themed restaurant in Tokyo, the city where Team Sonic and Shadow face off for the first time. Fowler felt using the characters in a popular attraction was believable, and could be used as a plot device, such as when Team Sonic needed to have a moment to regroup and have a conversation about what was going on. Miller said that one main challenge of adapting the story elements of Sonic Adventure 2 was balancing the darkness with the mandate to keep the film family-friendly, and that another was to adapt the story elements for the timeframe and narrative of the film series; Casey said that two obvious examples were that the concept of Gerald, Maria and Shadow living in the ARK space station as they did in the games would be incompatible with the setting of the 1970s, and discarding Maria's terminal illness from the games as for this story it was not needed.
To write the dual roles of Gerald and Ivo for Carrey, Fowler said they initially focused on parallels between his two characters, "not just with bald heads and giant mustaches, but also in their behavior and their attitude"; they then decided they needed to "create the right sort of conflict" for the film. Casey said Carrey embraced the story of Gerald's "toxicity" affecting Ivo, who "regresses into a little kid", and said that the "hurt" the film reveals Ivo experienced gave the story more emotion. Miller described their role in writing the script for Carrey as building "an arena for him to kind of go bonkers and come up with all these ideas", and that much of the characters' humor was conceived by the actor himself, and Casey described his and Miller's writing as a "framework" for Carrey.
Casey said he and Miller had considered writing in the line "guns, lots of guns" for Shadow to say in an homage to voice actor Reeves having two characters, Neo from The Matrix and John Wick, who said the line before—though they decided against it, instead ending up with the film referencing the Reeves film Speed (1994) and the choreography of Sonic and Shadow's final duel mimicking that of Neo and Agent Smith's fight at the end of The Matrix. Fowler felt that the world did not become "edgy" with Shadow's character, but said the tone the character brought made the films more exciting and dangerous. He acknowledged the elements of firearms and Shadow's motorcycle in his eponymous 2005 video game, and said that they were "very respectful about what fans expect to see and what they love about the character", and that he and his team were cognizant of how to properly incorporate that imagery into a family film. Fowler explained that the inclusion of a reference to the TikTok meme "Shadow loves Latinas" in the film was a way to "honor what fans know and love" about the franchise's history of being the subject of online shitposting. Initially being unaware of the meme and its popularity, Juan / Pablo actor Cristo Fernández mused the appreciation of it was tied to the appeal of telenovelas, the medium with which the meme was implemented in the film—Shadow watches the in-universe telenovela La Última Pasión, and is "enamored" with the character Gabriella.
Second-unit filming began in late July 2023 for animated characters only without physical actors—as a result of the 2023 SAG-AFTRA strike—in Farnham, Surrey, England. Principal photography was originally scheduled to begin on August 31, 2023, in London, England, but was delayed to September. Production with physical actors started on November 29, 2023, and was announced with a teaser image of Shadow the Hedgehog's stand-in statue used in filming. Brandon Trost returned as cinematographer, and Luke Freeborn was production designer. Schwartz began recording for the film by mid-February. Marsden said that filming had been completed by March 14, 2024, while Fowler officially revealed that the film had wrapped production on March 29.
Fowler said that asking Carrey to play the dual role of Ivo's grandfather Gerald was "such a big ask", and meant Carrey had to spend three hours in a makeup chair being physically prepared to play Gerald each time. Carrey also helped design the prosthetics he wore. While Carrey performed each role, actor Brendan Murphy doubled for the other character. During each performance, Carrey informed Murphy how he would be doing the other, a system the former said was "very technically difficult", especially considering that he was interacting with a pre-recorded voice track of the opposite character during his performances. Star Cristo Fernández said that he had not had the opportunity to meet Carrey—a childhood hero of his—nor Reeves during production, as his portion of the film was shot separately from all the other actors.
Fowler said that Reeves "would just give us so many different versions of line readings and just want to keep going" during voice recording and said he put more into his performance than "just sort of showing up and reading the script into a microphone", both understanding their vision for the film and realizing his interpretation of Shadow; Reeves was prepared with questions to give himself insight about what the team was trying to achieve. Animation supervisor Clem Yip said Reeves's low-key, serious vocal performance informed their visual work. As opposed to acting with a placeholder tennis ball in scenes with Shadow, Browne shot scenes with a Shadow puppet, with his puppeteers ad-libbing certain lines into the film. Fowler explained that "it really takes skill and imagination to create a believable performance" with there not being "really anything" to act with in scenes—something the other performers had to accomplish—and remarked that he was impressed with Browne's mastery of this at her young age. In creating the action sequences involving Shadow, Fowler paid homage to the 2005 Shadow the Hedgehog game by adapting several of its action scenes in the film. Fowler previously worked as an animator on the 2005 game, and felt honored to adapt the character for the screen.
As a cost-cutting measure, the producers had an in-house animation team at Paramount work on both Sonic the Hedgehog 3 and the Knuckles series. Clem Yip serves as animation supervisor, while Al LeVine serves as film editor. Animation was produced by six studios: Rising Sun Pictures, Rodeo FX, Industrial Light & Magic, Fin, Marza Animation Planet and an in-house team at Paramount. Fowler's team took a "speedboat vendor" strategy, dividing the animation work across these six studios. Fowler emphasized the need for visual continuity between the projects and cited communication as critical to this mandate.
According to Ascher, the team "made an investment in the Sonic assets and [...] built them in-house," then distributed them to the vendors, which he noted was comparatively different from previous installments where "usually the vendor controls the assets that they rig". Owning the assets also allowed for their in-house team to work exclusively on Sonic the Hedgehog 3 and Knuckles, and helped the production "keep costs down and move faster." Fowler said that the multi-studio process meant there were more parties "you have to bring up to speed, so initially there's an extra level of work that has to be done". He said that once this was achieved, the flexibility allowed his team to tweak the finer aspects of the production and the performances.
Tom Holkenborg, who composed the score for the first two Sonic films, returned to score Sonic the Hedgehog 3 and had finished work by July 2024. In December 2023, Crush 40 vocalist Johnny Gioeli said there had been talks of including "Live & Learn", the theme song from Sonic Adventure 2. In February 2024, Gioeli confirmed "Live & Learn" would be included in the film. Jelly Roll released a single for the film, "Run It", on November 21, 2024. The film also features the song "Neon" from Japanese rock band One Ok Rock, who previously contributed to the soundtrack for the 2022 game Sonic Frontiers. The soundtrack album was released by Milan Records on December 20, 2024.
Sonic the Hedgehog 3 premiered at the Empire Leicester Square in London on December 10, 2024, and at the TCL Chinese Theatre in Los Angeles, California, on December 16. It was released in the United States by Paramount Pictures on December 20, 2024, taking over the original release date of Smurfs (2025). Paramount held a fan event on December 19 for early screenings at theaters in premium formats.
In April 2024 at CinemaCon, Paramount showcased first-look footage of the film, which featured a heavier Robotnik bemoaning his current state before Agent Stone informs him that "they found him", and Sonic, Tails, and Knuckles fighting a silent Shadow. In July, a popcorn bucket and action figures produced by Jakks Pacific were leaked online. On August 25, the first official tease of Keanu Reeves's involvement as Shadow was posted to the film's TikTok account, which referenced the actor's mention in the first film, captioned "foreSHADOWing". Beginning at that time, images of the film's characters were projected on buildings in locations globally in promotion of the film's first trailer, which released on August 27 alongside a teaser poster. Reeves's role was considered the most prominent feature in the trailer. IGN observed that "Keanu Reeves is very much in Keanu Reeves mode here", and Vulture likened the actor's moody and vengeful portrayal of Shadow to a John Wick performance. Ash Parrish of The Verge agreed that Reeves's voice was satisfactory, and also noted Maria's reveal, anticipating how the film would adapt her fate.
On the opening weekend of Paramount's Transformers One, posters of Shadow were raffled to the first 300 attendees at select theaters, with Reeves signing a limited quantity of them. In commemoration of Halloween, a 10-second clip from the film of Shadow saying "boo" was posted on social media. On November 4, a promotional still image of Shadow was released by Fandango. On November 18, a new poster was released, featuring the main team, the Robotniks, and Shadow, who looms above the cast at the top and also rides his Dark Rider motorcycle at the bottom. Several press outlets were also sent a Sega Genesis cartridge containing promotional posters and voice lines from the characters, as well as a minigame through which the date for the film's second trailer could be unlocked by inputting a cheat code from the game Sonic the Hedgehog 3 (1994); ↑ ↑ ↓ ↓ ↑ ↑ ↑ ↑. The trailer was released on November 25. Commentary focused on Shadow's use of a gun in one scene, considering the prominence of firearms in the 2005 Shadow the Hedgehog game and Sega's subsequent disownment, as well as Tails being mistaken for the Pokémon character Pikachu. The phrases "HE HAS A GUN" and "HE PISSED ON THE MOON" began trending on social media following the trailer's release, with the latter being a reference to the popular web series SnapCube's Real-Time Fandub.
By October, the Jakks Pacific toy merchandise was released. The shoe company Reebok produced a tie-in line of sneakers in promotion for the film, and McDonald's will sell Happy Meal toys of the film's characters. AMC Theaters produced a novelty popcorn bucket of Sonic's head and a collectible combo of a cup, drink topper, and a mask. On December 11, 2024, Paramount also released several posters parodying numerous Christmas films. The original "Ugly Sonic" design from the first film that received backlash was featured as a sweater design that would be given away as a prize. A stop-motion short, "A Very Sonic Christmas", was released on December 11, 2024, with Schwartz, Elba, O'Shaughnessey, and Reeves reprising their roles, and Wade Whipple actor Adam Pally voicing Santa Claus. A tie-in video game, Shadow Generations, was released in October 2024. The Sonic Team head, Takashi Iizuka, said he wanted to "spotlight Shadow as a character". Downloadable content based on the film was released on December 12, with an additional level set in Tokyo as it appears in the film; during the level, Shadow's appearance changes to resemble his movie counterpart, with Reeves reprising his voice. Reeves and Fowler gave an interview on CBS Mornings to promote the film.
Sonic the Hedgehog 3 was released for digital download on January 21, 2025, and will release on Ultra HD Blu-ray, Blu-ray, and DVD on April 15. 4K SteelBook options include an edition with Sonic on the cover, and an Amazon retailer-exclusive version with Shadow on a red lightning bolt pattern background. Special features content include audio commentary with Fowler and Schwartz, a feature with Reeves and the cast discussing Shadow, a segment in the recording booth with Schwartz, Elba and O'Shaughnessy, and the "A Very Sonic Christmas" special. The film began streaming on Paramount+ in the United States and Canada on February 18, 2025. Upon the film's digital release in the UK, it debuted atop the Official Charts Company's Official Film Chart.
As of March 23, 2025, Sonic the Hedgehog 3 has grossed $236.1 million in the United States and Canada, and $255 million in other territories, for a worldwide total of $491.1 million.
In the United States and Canada, Sonic the Hedgehog 3 was released alongside Mufasa: The Lion King and was projected to gross $55–60 million from 3,800 theaters. The film made $6.5 million from Thursday night previews, setting a record for the Sonic franchise. On Friday, the film grossed $25.7 million, a slight decrease from Sonic the Hedgehog 2, which made $26.3 million. The film went on to gross $60.1 million during the three-day opening weekend, topping the box office and achieving the second-highest weekend debut for a PG film in December behind 2005's The Chronicles of Narnia: The Lion, the Witch and the Wardrobe ($65.6 million). In its second weekend, Sonic the Hedgehog 3 retained the top spot at the box office with $37 million. At this point, the film's $136 million domestic box office total brought Reeves's lifetime domestic box office earnings over the $3 billion threshold.
The film finished in second place behind Mufasa: The Lion King in its third weekend with $21.4 million. The film finished in third place behind Mufasa: The Lion King and Den of Thieves 2: Pantera in its fourth weekend with $11.3 million.

In its seventh, it reached a worldwide total of $462.5 million, making it the second-highest-grossing video game film of all time, ahead of Pokémon Detective Pikachu (2019) and behind The Super Mario Bros. Movie (2023). By March 4, the film grossed $485.7 million, overtaking Bruce Almighty (2003) as Carrey's highest-grossing film.
On the review aggregator website Rotten Tomatoes, 85% of 142 critics' reviews are positive, with an average rating of 6.60/10. The website's consensus reads: "With a double helping of Jim Carrey's antics and a quicksilver pace befitting its hero, Sonic the Hedgehog 3 is the best entry in this amiable series yet." Metacritic, which uses a weighted average, assigned the film a score of 56 out of 100, based on 28 critics, indicating "mixed or average" reviews. Audiences polled by CinemaScore gave the film an average grade of "A" on an A+ to F scale, matching with the previous two films' grades, while those polled by PostTrak gave it an 89% positive score.
Reeves's and Carrey's performances received praise. Variety's Owen Gleiberman said that Reeves' "tones of deepest resonance" made Shadow empathetic to the audience, and that Jim Carrey topped his previous work with his roles as the Robotniks. Screen Rant's Rachel Labonte named Reeves's Shadow the standout of the film, saying the actor was brilliant at conveying the character's "hurt and steel". ComicBook.com's Marc Deschamps wrote that Reeves perfectly portrayed Shadow, with his brooding and darkness mixed well with the film's humor. He said while Gerald and Ivo largely served as comic relief, their relationship also contextualized Ivo and Agent Stone's characters, and that the film made a great ending for Robotnik. The New York Times's Glenn Kenny felt Reeves brought "suitable emo brooding" to Shadow, and felt that Carrey's "virtuoso double act" was "bombastic". IGN's Matt Donato said that Reeves's own identity—already reflected in the character by his voice—profoundly paralleled the tragedy in Shadow's story considering Reeves had experienced "unthinkable" hardships in his life; Donato concluded that Reeves "is Shadow the Hedgehog".
The A.V. Club's Matt Donato wrote Reeves added "stoic somberness" to the established cast and noted Carrey's doubling up of the "looniness", and The Hollywood Reporter said that Reeves brought the same gravitas to Shadow that he did to John Wick, feeling his delivery of "quiet condescension" made him "all the scarier for the lack of overt menace". It praised Carrey's jokes, but questioned the returning human characters. Polygon's Jesse Hassenger said Carrey's "gloriously deranged one-man, two-character musical" contrasted with the "utter sincerity" of Reeves, who made Shadow a "weirdly likable little ball of pain". In contrast, The Guardian's Andrew Pulver was ambivalent or critical about most of the performances and said the film would have been "a lot, lot worse" without Carrey, while Deadline Hollywood's Pete Hammond felt Carrey's fourth wall breaking was not as impactful given Ryan Reynolds's exceeding success with Deadpool. The Observer's Wendy Ide wrote "two Jim Carreys, each of them turning every individual line of dialogue into an extravagant pantomime of gurning and grandstanding, is categorically one too many".
Fowler's filmmaking and the CGI received a generally positive reception. Donato said that Fowler's direction made the lore in the film "digestible", Hammond felt Fowler's grandeur was in excess, though admitted that audiences would not find this a problem, and Labonte said Fowler succeeded in expressing Shadow's story in an emotional and engaging way. Donato said that the animation was executed successfully and uniformly such that one could not tell there were six separate studios working on the project. Kenny felt the "teeming computer graphics gadgetry of death and destruction" was "bombastic". A. A. Dowd of IGN said the CGI was "much more pleasing" in this installment. IndieWire's Christian Zilko criticized the CGI, feeling the characters never fit in a given scene, and said Fowler's work was mediocre.
In September 2024, producer Toby Ascher stated intent for additional Sonic films. Elba and Reeves have expressed interest in a spin-off starring their characters. In December 2024, a fourth Sonic film entered development, set for release on March 19, 2027. Despite his character's apparent death in Sonic the Hedgehog 3, Carrey said in January 2025 that he was "open to the idea" of returning for the fourth film, provided that its premise interested him.
