I can think of one, no actually TWO, French actors you may have heard of, who fall into this category:
Alain Delon: now, you'll never catch HIM smiling, too damn self important for that. And he is at the political extreme right.
Gérard Depardieu: sorry, can't bear him. He loves himself, in fact he never ACTS, he is always his over the top self. (I only liked him in "Cyrano de Bergerac")
And yes, Tom f***ing Cruise, anytime!
