Despite Clair Obscur: Expedition 33 voice actor Charlie Cox's experience acting on screen, he has his own idea of how to depict his character Gustave in a film adaptation of the game, and it matches several fancasts.

Speaking to GamesRadar ahead of the BAFTA Games Awards, Cox expressed that he'd love to portray Gustave again in an Expedition 33 movie, but had a funny suggestion on how to approach the character, saying that "they should get Robert Pattinson to play the part, and I should do the voice. Because then they would have pretty much the exact Gustave from the game."

Look at online comments about Gustave (or use your own eyes), and you'll see that the resemblance between the character's face and Pattinson is quite evident. Cox is probably joking about wanting to dub his voice over The Batman star, but he isn't wrong in saying it would be a hilariously accurate depiction of the character.

"I just think Gustave looks like Rob," Cox added. Glen Powell better watch out if he wants that role.

Cox remained modest about his contributions to the game, which went home with the Best Game honor at the BAFTAs, saying his "involvement with this, as minuscule as it was originally and how it's now expanded so much, has been nothing but an incredibly humbling and enjoyable experience." He recently revealed that he finally played the game but admitted he's "not very good" at it.

In regard to whether an Expedition 33 movie will actually happen, the self-proclaimed "franchise farmers" at production company Story Kitchen announced in January 2025--before the game released--that a film adaptation was in development. There's been no official word on the project since then, but Story Kitchen's credits include the Sonic the Hedgehog films and the upcoming Tomb Raider show for Prime Video.
