I saw Dark Knight this weekend... everything you've heard it true... and more. In my humble opinion (hahaha) Mr Ledger should be nominated for Best Actor, not Supporting... it's his movie! I wonder if they "enlarged" his part after his death?
His black humor was over the top, the quirky mannerisms he created for the character were very creepy and he was definitely the most charismatic part of the movie! Plus the scene where's he's in the "naughty nurse" uniform is one of my favorites!
