"When you're playing the good guy, you want to find the dirty parts - and when you're playing the bad guy, you want to find the vulnerability."

'The Dark Knight,' for me, has the same problem that every other 'Batman' movie has. It's not about Batman. I think Heath Ledger is just phenomenal and the character of the Joker is beautifully written. He has a particular philosophy that he carries throughout the movie. He has one of the best bad guy schemes.
