Simon Kinberg to Collider:

“You are absolutely right [that this is a different version]. There are elements that are similar, but it is different in tone, almost in sub-genre—one of the things that we’ve done with these standalone movies […] is that we’ve tried to create sort of sub-genres within the superhero genre when it comes to these standalone movies; even Deadpool itself is like a raunchy R-rated comedy, not just a superhero film. So Gambit became something different over the span of developing it with Channing, with his partner Reid [Carolin], with Josh Zetumer the screenwriter. It is something that we intend to make but listen I’m Jewish, so my expectation for everything is I don’t believe anything until it’s out in movie theaters. So I share your cynicism generally, but in this particular case we’re working very hard to get the movie going.”
