Mister Sinister Confirmed to Appear in Wolverine 3
The mysterious post-credit scene for X-Men: Apocalypse delivered a nice teaser for fans with the reveal of “Essex Corp,” which naturally means the villain Mister Sinister is on his way, but to which film? Writer/producer Simon Kinberg previously said it could be a teaser for any number of X-Men movies, but on the commentary track for Apocalypse (as discovered by Cinema Blend), Kinberg and director Bryan Singer revealed that the villain will appear in Wolverine 3.
Given the cast of the film, there are a number of choices for who could be playing the villain in the film, including Boyd Holbrook (possible), Richard E. Grant (likely), or even Stephen Merchant (probably not). We know that the primary villains for the film will include both The Reavers, as well as Wolverine’s favorite group, Weapon X. It stands to reason that Sinister’s role in the film will be tied to the creation of X-23, the young female clone of Wolverine also along for the film’s road trip, which makes the post-credit scene for Apocalypse finally make some sense.
