40 hours of lines, in an accent and unprepared: Charlie Cox, Gustave in 'Expedition 33', has already recorded a secret Sega game — and fans are betting on Persona 6

Charlie Cox is far from done with video games. Speaking to IGN at New York Comic Con, the actor, who made his gaming debut as Gustave in 'Clair Obscur: Expedition 33', revealed he has already recorded around 40 hours of lines for a new Sega game. 'I had to do 40 hours or whatever it was,' he said, joking that he now faces '40 hours of lines I've not prepared in an accent.'

The actor did not reveal the title, but said the project 'doesn't have a name yet', a sign that an official announcement may still be a long way off. According to Kotaku, the sheer amount of recording and teases throughout the summer have led fans to speculate about Persona 6, the next chapter in Atlus's RPG series, which belongs to Sega. None of this has been confirmed so far.

Cox's gaming debut could hardly have gone better: 'Expedition 33' racked up several awards and made Gustave one of the game's most memorable characters. The reveal comes the same week the actor was in the NYCC spotlight for 'Daredevil: Born Again', the Marvel series in which he plays the Hell's Kitchen hero.
