I've lost my enthusiasm over this film about a month ago. I'm almost 100% certain that the X-Men movies will be re-booted as soon as 2019-2020, which makes 'Gambit' almost pointless.
Not saying this film won't be made. None of the articles have stated that, and Verbinski was in talks to direct it, not sure if it was ever official?
Personally I'd rather see Gambit introduced in an X-Men film, then again, we might have to wait 3-4 films for that to happen. So yeah, it's a strange situation...
