Charlie Cox has recorded 40 hours of dialogue for an unannounced Sega game

Charlie Cox, fresh off his award-winning turn as Gustave in Clair Obscur: Expedition 33, revealed at New York Comic Con 2026 that he's already deep into voice work for an unannounced Sega game — one that doesn't even have a name yet.

Speaking to IGN at NYCC, Cox confirmed the role is substantial, requiring around 40 hours of recorded dialogue. There was a catch: the studio wanted an American accent, and Cox — very much English — only found that out on day one. "I showed up for the first day, and I was like, 'Hi guys, nice to meet you! How are you?'" he recalled. "And all of them went, '…oh, he's English.' They'd wanted him to be American. But now I've got to do 40 hours of lines I've not prepared in an accent." Cox had previously said earlier this year that he planned to take on more gaming projects after Expedition 33.

The sheer volume of dialogue and Sega's involvement have sent fans straight to one conclusion: Persona 6. Atlus, a Sega subsidiary, has been teasing the next entry in its mega-hit JRPG series over the summer, and a 40-hour voice recording session fits the scale of a mainline Persona game. That said, Cox himself noted the game has no name yet, leaving open the possibility it's something entirely unannounced.

Cox won multiple awards for his Expedition 33 performance, so landing another major gaming role is no surprise. Whether it turns out to be Persona 6 or something else entirely, the project is clearly well underway.
