PS: I also like ROMPER STOMPER (Crowe plays a real racist asshole in that one) but one film you probably should have included is another early Crowe film: THE SUM OF US. Crowe plays a gay guy (who is unlucky in love-?!) with a winning naturalism. One of his best.
I loved him in both gladiator and a beautiful mind but I would have to go with a beautiful mind. It's just too good. What a performance!
I also agree that he should not have won for Gladiator. Tom Hanks should have won his third oscar for "Cast Away" in 2000. Russel Crowe should then have won in 2001.
