One of my favorites is Bradley Cooper, he isn't stuck in just one genre and he's gorgeous while still being the nice guy.
Ellen Page! Saw her for the first time in "Hard Candy" and was seriously impressed. Still love her work, she brings such an honesty to her acting. There isn't a false bone in her body!
I love Jack Nicholson. There is no other actor who could be nominated for an oscar for a fifteen minute role in a movie.
