Marlon Brando

Humphrey Bogart: I came out here with one suit and everybody said I looked like a bum. Twenty years later Marlon Brando came out with only a sweatshirt and the town drooled over him.

No actor would argue with this choice.Where you place the also-rans is very subjective.

SIMPLY THE GREATEST FILM ACTOR OF ALL TIME!!

His twenty minutes in The Godfather is the greatest acting class you'll ever see,especially the undertaker scene.This kind of perfection wont be matched in a long long time.

just watch his performance in the godfather. No one has ever acted that good and no one ever will. that is simple the best performance of all times and will always be.
