X-Men: First Class Enrolls Oliver Platt

This movie is huge! Every week, we feel like we are announcing yet another star in the movie!
This morning, the news is that Oliver Platt will be joining the cast of X-Men: First Class.
Not much is known about his character, only that he is referred to as The Man In Black and is not a mutant.
So, does that also mean he can’t turn into a smoke monster or fight crime alongside Will Smith?
Just curious.
Thoughts?
