Look out Patrick Stewart, McAvoy's biting your look. Of course, there's no coincidence here. McAvoy has already played Professor Charles Xavier (a role first brought to the screen by Stewart) in two movies. But as the character keeps aging, it has become necessary for McAvoy to commit to Professor X's (and P-Stew's) iconic chrome dome style. If you ask me, he pulls it off. But also, I just love Professor X.
