Not only is the film (reportedly) looking to introduce Mister Sinister finally, it may also bring Daniel Craig into the mutant world.
Daniel Craig is reportedly being eyed by Twentieth Century Fox to play the main villain in Gambit, and possibly beyond in the X-Men universe.
So, before people get too attached or disinterested in the idea of Craig joining Gambit as Mister Sinister, it is just a rumor right now and could never happen.
Splash Report is reporting that their sources have informed them that there are “conversations” to bring Craig onboard for Gambit.
