10 Actors You Forgot Were In The X-Men Films

4. Oscar Isaac – Apocalypse

Oscar Isaac, who was one of the three leads in the most recent trilogy of that little-known property Star Wars and has also been in smaller classics such as Ex Machina, played Apocalypse, arguably the X-Men's biggest villain after Magneto. Remember that? No, didn't think so.

There are two pretty obvious reasons as to why that is. The first is that Isaac was covered in make-up so that he actually looked like the character and on top of that did a voice that was rather different to how he usually sounds. The second is just how unremarkable and therefore forgettable X-Men: Apocalypse was, and how the version of Apocalypse it featured was appropriately lacklustre.

One can only hope that Isaac got a nice pay check for the job.
