Dicaprio got robbed with Gilbert Grape. That was about the most brillant acting I've ever seen, I thought he was actually down's or something.
Winslet got robbed too, with Titanic, and probably this other one as well. I saw the clips of DiCaprio and thought he looked pretty darn impressive, a good strong second at least to Foxx. As as actor, he is very good. His day will come.
