Everyone picked up on the nod to Mister Sinister at the end of X-Men: Apocalypse (here) and assumed that he was set to be the villain in the next X-Men outing, but it seems we’ll have a shorter wait to see him causing problems in the X-Verse.
Director Bryan singer has confirmed on the X-Men: Apocalypse commentary the sinister will be the villain in Wolverine 3.
The set up for the character occurs n apocalypse in the post credits scene where we see men in suits taking viles of wolverine’s DNA away in a suitcase with Essex Corp. on it. In the comics Essex Corp is owned by Nathaniel Essex, a.k.a. Mister Sinister.
In the comics Sinister is virtually immortal and over time has stolen the powers of other mutants so he has a host of abilities at his command.
There’s speculation that Richard E Grant – who we know plays a mad scientist in the movie – may well be Essex and, as a massive fan of Grant’s, I think this would be spectacular.
Wolverine 3 – believed by many to be Old Man Logan – is set for release on March 3rd, 2017.
