Patrick Stewart as Professor Xavier
It doesn’t matter that they replaced Professor Xavier with a new actor we won’t mention on this list (because we’re too heartbroken that they didn’t get Patrick Stewart to reprise the role). Sir Patrick Stewart will always be Professor Xavier in our hearts, as well as Captain Picard from Star Trek.
He played the professor who owned a school that was designed to teach mutants how to train their powers and use them for good. In the comics, the defunct school was reopened as Jean Grey’s School for Higher Learning. Does that mean there will be an X-Men Goes to College movie coming out? Only time will tell.
