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.

I think up to this point, it's been difficult to suggest a world where Batman and Superman and Wonder Woman and others could exist in the same universe. That was one of the things I really wanted to try and get at. Not to mention, the amazing opportunity to bring those characters and have those characters tell an important story, their own story, within the confines of a film.

I aim my movies, as much as I can, at myself. I think that those movies have an interesting quality. They're very movieish. They are movie movies. Like I think Watchmen is a very self-aware movie. 300. Dawn of the Dead definitely. That's really where I've ended up.

I think Sin City is a good example. Nobody would accuse Sin City of being historically inaccurate because it takes place in modern times.

I imagine the film ["300"] as if I was a Spartan and I had never seen an immortal or a Persian, or an elephant or a rhino for that matter.

The challenge with 'Watchmen' is making sure that the ideas that were in the book got into the movie. That was my biggest stretch. I wanted people to watch the movie and get it. It's one of those things where, over time, it has happened more.
