Rumor status: Moderate confidence, still unconfirmed.
A long-running GTA VI casting rumor began with Matty Matheson, the actor, chef, and co-star of The Bear. In a late-2023 interview clip reported by outlets including NME, Matheson appeared to say that he had worked on the next Grand Theft Auto before catching himself and suggesting he might not be allowed to discuss it.
That is the entire foundation of the claim: a public comment from Matheson himself, not a Rockstar Games announcement, cast list, credit database entry, or officially released character reveal. It is a more substantial starting point than an anonymous social-media post, but it does not tell us whether he plays a named character, provides a brief voice cameo, appears only through likeness or performance capture, or even remains in the final game.
Rockstar has not confirmed Matheson’s involvement in GTA VI. Its official GTA VI material has introduced Jason, Lucia, and several supporting characters, but it has not published a full voice or performance-capture cast list. Until that changes, this should be treated as an unconfirmed casting report—not proof of a celebrity role.
What Matheson actually appeared to claim
The attention comes from Matheson’s own remarks, rather than from someone claiming to know a friend of a friend at Rockstar. In the exchange, he seemed to indicate that he had participated in the new Grand Theft Auto, then became noticeably cautious about saying more.
That reaction is understandable in an industry where nondisclosure agreements are common. Voice, facial-performance, motion-capture, music, and promotional work can all be covered by confidentiality terms. But players should avoid filling in the blanks for him.
His comment does not establish any of the following:
- That Matheson plays a major story character.
- That he is portraying himself in Leonida.
- That his likeness will appear in the game.
- That he recorded dialogue for a radio station, mission, cutscene, or online mode.
- That his contribution survived revisions and will be present at launch.
Those are all different kinds of work, and public discussion has often blurred them together. A recognizable performer could have a tiny role that players never notice, while a named character could be voiced by someone whose identity is intentionally withheld until much closer to release.
Why the claim has more weight than a typical “insider” post
The strongest part of this rumor is straightforward: the alleged source is the person said to be involved. Matheson has an established acting career, and he made the remarks publicly rather than hiding behind a burner account. That gives the report a reasonable basis for discussion.
There is also a practical reason to take the possibility seriously. Rockstar’s games have a long history of using actors, comedians, musicians, radio personalities, and performers from outside conventional game voice acting. A Matheson appearance would not be out of character for the studio’s casting approach.
Still, plausibility is not confirmation. It is possible that he misspoke, referred to an audition or earlier recording session, was discussing a role that changed during production, or simply used loose wording in a casual conversation. None of those possibilities requires assuming bad faith; they are normal reasons to be careful with early entertainment casting claims.
What official GTA VI information does—and does not—settle
Rockstar’s official GTA VI page is the source that matters for confirmed game information. Its trailers and character material establish the setting, the central duo of Jason and Lucia, and a collection of characters around them. They do not identify their actors in a complete, official credits-style format.
That silence is not evidence for or against Matheson. Studios routinely hold cast details back, particularly where revealing an actor could expose story roles, celebrity cameos, character relationships, or other marketing plans.
It is also worth separating this claim from the unrelated question of who voices Jason or Lucia. Matheson’s comment did not reliably identify either protagonist, and there is no sound basis for using it to “solve” the leads’ casting. Matching voices to actors from trailers is entertaining community detective work, but it is not reliable sourcing.
Rumor credibility
Classification: Moderate confidence, still unconfirmed.
Here is why this sits above low-confidence rumor territory:
- Identifiable origin: The claim traces back to Matheson’s own public remarks, rather than a repost chain with no beginning.
- Relevant context: Matheson works as an actor and has participated in high-profile productions, making a game-performance role plausible.
- No official contradiction: Rockstar has not publicly denied the claim.
But the ceiling is equally important:
- No Rockstar confirmation: There is no announcement, press release, trailer credit, or verified cast listing from Rockstar that names him.
- No role details: The original remarks do not establish the size, format, or final status of any contribution.
- No independent production evidence: Public reporting has not supplied documentation that would turn this into a confirmed casting credit.
That combination is why “possible GTA VI contributor” is a fair description, while “Matheson is definitely in GTA VI” goes too far.
Why this matters to players and creators
Celebrity-casting rumors can be fun, but they can also create misplaced expectations. A recognizable name attached to GTA VI can quickly become a made-up mission rumor, a fabricated character render, or a fake “leaked” dialogue clip. Those posts tend to travel faster than corrections—especially when AI-generated imagery and synthetic voice audio can make ordinary hoaxes look convincing at a glance.
For creators, streamers, and community managers, the safe approach is to label any Matheson-related GTA VI content as unconfirmed and avoid using alleged leaks as proof. Do not present fan-made character art, AI voice samples, or supposed casting screenshots as authentic materials. That protects audiences and avoids building projects around a detail Rockstar may never validate.
For future PC modding and FiveM communities, the practical impact is currently close to zero. Even if Matheson is in the finished game, it does not reveal anything about GTA VI mod support, roleplay tooling, downloadable assets, multiplayer policy, or the eventual PC version. It is a casting possibility, not a technical roadmap.
What would move this from rumor to confirmation?
The cleanest confirmation would be a Rockstar announcement, official game credits, a verified interview in which Matheson can discuss the work openly, or a reputable production credit that Rockstar does not dispute. A trailer appearance alone could help, but only if it clearly identifies him or is accompanied by official context.
Until then, there is no need to turn a brief public comment into a full character biography. GTA VI has enough confirmed material to discuss without assigning performers to every face in a trailer.
