GTA 6 voice cast: who is confirmed so far

The short answer

Rockstar has not confirmed who voices Jason or Lucia. As of mid September 2026, exactly one actor has confirmed his own involvement in Grand Theft Auto VI: Stephen Root, best known for voicing Bill Dauterive and Buck Strickland on King of the Hill. He said so himself, in an interview, not Rockstar. Every other name attached to the GTA 6 cast online is a guess, and this page treats it that way.

Role	Actor	Status
Jason Duval	Not known	Unconfirmed
Lucia Caminos	Not known	Unconfirmed
Brian Heder	Stephen Root	Confirmed by the actor himself

Officially confirmed

Rockstar itself has not named a single voice actor for GTA 6. Nothing in this row comes from Rockstar. The one confirmation on this page comes from the actor, not the publisher, so it is listed here as confirmed by its source, with that source named plainly.

Claim	Where it comes from
Stephen Root confirmed his own role in GTA 6	Reported by IGN, quoting an Associated Press interview with Root, published around 14 September 2026
Root is understood to voice Brian Heder, a character seen in Trailer 2 and An Extended Look	GTA Wiki’s Brian Heder entry, citing the same AP interview; IGN reports fans identified the character by matching Root’s distinctive voice to footage, which Root’s comments did not contradict
Jason Duval’s voice actor is, in GTA Wiki’s own words, “yet to be officially revealed”	GTA Wiki’s Jason Duval entry
Lucia Caminos’ voice actress is, in GTA Wiki’s own words, “yet to be officially revealed”	GTA Wiki’s Lucia Caminos entry
Rockstar has not confirmed any GTA 6 actors	IGN, 14 September 2026: “Remarkably, Rockstar has yet to confirm any GTA 6 actors, leading fans to try to work out the cast for themselves. We don’t even know who plays Jason and Lucia.”

Press reported

There is nothing to put in this section that meets this site’s bar. Every other name that circulates for Jason, Lucia, or any other GTA 6 character has not been traced to a named, on the record statement from the actor or from Rockstar. Rather than repeat an unsourced name here under a softer label, this page leaves the section empty and says why.

How to tell a confirmed casting from a rumour

This is the part worth being careful about, because GTA 6 cast lists are one of the most guessed-at topics anywhere in the coverage.

• A confirmed casting has a name attached to a quote. Stephen Root did not get added to a wiki table by a fan. He told the Associated Press, on the record, “Yeah, you’re gonna see me in it.” That is a primary source: the actor speaking for himself.
• A rumour usually has no primary source at all. It spreads through voice matching by ear, screenshots of old casting-call listings, or IMDb pages that anyone can edit. None of those are the same as an actor or Rockstar making a statement.
• Even a real confirmation can carry an unconfirmed detail. Root confirmed he is in the game. The specific character he plays, Brian Heder, was worked out by fans and reporters matching his voice to footage, and Root’s comments did not deny it. That is a reasonable inference from a named source, not the same as Root or Rockstar naming the character outright, so it is presented here with that distinction kept visible.
• A long, detailed cast list with no sources is a warning sign, not a reassurance. The more precise and complete an unsourced list looks, the more likely it has been copied and expanded from other unsourced lists.

What is still not known

• Who voices Jason Duval.
• Who voices Lucia Caminos.
• Whether Rockstar plans to release an official cast list before launch, or only after release through the game’s credits.
• Whether any other trailer or Extended Look character has a confirmed actor beyond Stephen Root as Brian Heder.

How this page stays honest

This page lists exactly one confirmed voice actor, because that is what the sourced record shows. Rockstar’s own silence on the cast is treated as a fact worth stating plainly, not worked around with a long unsourced list borrowed from elsewhere. If Rockstar names an actor, or another cast member confirms their own role the way Stephen Root did, this page will be updated with that source named.
