At the end of X-Men: Days of Future Past, we saw a young Apocalypse building pyramids and watching his Horsemen. Now we know the man behind the hood will be Oscar Isaac (Inside Llewyn Davis, Sucker Punch). In the 2016 X-Men: Apocalypse, 1980s mutants will face the titular villain and the destruction that he rains down upon the Earth. I’m sure this will allow Isaac to bring that evil Blue persona back to the forefront. DANCE FOR HIM, MAGNETO! DANCE FOR THE HIGH ROLLERS!
You can see Isaac a little sooner when Star Wars: The Force Awakens opens in 2015.
