What actors can save a movie all by themselves?

[Temprano26]

You ever see a movie that wasn't great but with one awesome performance could be worth watching a second or third time?

I've been watching Robin Williams lately because his recent death is pretty hard to swallow. His performance was often the best thing about some of the movies he was in. I barely remember Popeye but Williams was so perfectly casted. Aladdin was a great movie from my childhood but without Robin playing the Genie it would have been just OK. He was one of the greatest entertainers who ever lived and we've really lost a national treasure this week.

Yes Robin Williams as the Genie "made" Aladdin.

Jack Nicholson as the Joker "made" Batman. And any movie he is in.

Christopher Walken can "make" any movie.

Maybe Paul Giamatti.

And William H. Macy.

And Ed Helms.
