When I make a live-action movie, it's a very physical process. It's like running a marathon.

The difference between 'Watchmen' and a normal comic book is this: With 'Batman's Gotham City,' you are transported to another world where that superhero makes sense; 'Watchmen' comes at it in a different way, it almost superimposes its heroes on your world, which then changes how you view your world through its prism.

I guess for me - in the TV commercial world I was known for shooting locations, beautiful landscapes and things like that - so, it's interesting.

When Reality is a prison, Your mind can set you free.

So you know when you were work on Man of Steel, in 10 years somebody is going to do the music for Man of Steel, and a different director is going to be doing Man of Steel. That’s the reality. So all you can do is to give it not only your best, but your vision on what this character is, when you become one with that character.

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 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.
