I think everyone who makes movies should be forced to do television. Because you have to finish. You have to get it done, and there are a lot of decisions made just for the sake of making decisions. You do something because it's efficient and because it gets the story told and it connects to the audience.
Limitations are something that I latch onto - like working in genre, or if you're writing TV, there are act breaks, there's a length of time it's supposed to be. The restrictions of budget and sets can be really useful. When you can have everything, it's very hard to make things feel real and lived in.
'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.
