Jerry Stiller >>>>> Ben Stiller
I think Brando has more range actually. On The Waterfront and A Streetcar Named Desire are incredible, as are films like Apocalypse Now and The Godfather. They are all testaments to his ability. Brando is one of the greatest actors of all time, and while De Niro is good I wouldn't place him in that elite category.
Also, John Candy rocks and I find Wes Anderson to be a bit of a hipster.
