Probably the hardest thing to do was the beginning of the movie ["300"], I think, when we were in Sparta and all that - just getting in the groove.

I mean, like, I can go in a room and say, look, 'Watchmen' should be at least 15 minutes longer than 'Batman.' I mean, that's, like, any geek will tell you that.

I'd say the purest experience for the movie is not to have read the book because I think when you've read the book you're just ticking off boxes. I think that after you see the movie, reading the book is a cool thing. I always say the movie's not meant to replace the book. That's ridiculous. I'm a huge fan of the book.

don't mean to sound weird but I get so immersed in the source material when I'm working on a movie that I kind of lose the line between what I thought of and what was in the book.

You know it has all the kind of fun stuff. It has the countermeasures - we always talk about the countermeasures because people are like, "What the heck is countermeasures?" You know if I shot a missile at it, flares would pop out of those holes and stop the missile from hitting it.

We've tried as hard as we can into keep the ideas intact in the hail storm that is Hollywood, so, whether he is or not, I'm personally proud of what I've been able to jam down their throats.

I've ended up as a filmmaker who really loves the movie part of movies. That time in my life was a big influence on the kind of movies that I ended up making. I always think I'm going to make a movie that's gritty and real, but then I make a movie that's like an opera. I fight it at first and then that's just the way it is.
