One of the things I think is important about 'Watchmen' is that it have resonance within cinematic pop culture as well as superhero culture.

It's interesting now that basically a CG set is the same cost as a real set. So like if you're going to build a CG house in the suburbs, it costs you $200,000. And if you were going to build it in a computer, it'll cost you $200,000. It's the same... the relationship is exactly the same.

We can deny angels exist, convince ourselves they can't be real. But they show up anyway, at strange places and at strange times. They can speak through any character we can imagine. They'll shout through demons if they have to. Daring us, challenging us to fight.

I always say 300 is a sci-fi movie as much as anything. It's like that could be another planet. It doesn't have to be earth necessarily. That's like when people get so wrapped up in the politics of 300 I always go, "By the way, that's a sci-fi movie. It's not really a historical film."
