We've tried to make a Superman movie where he does stuff and you go, 'Yeah, if I was Superman, that's what I'd do.' Even though he's an alien, he's more relatable, more human.

We tried to approach this as though there's never been a Superman movie before, but at the same time respecting the canon and mythology. There are the pillars that you have to respect, and I'm not about to break them. But it is fun for me to bend them and mess with them.

The thing about owls is that they do sort of have this facial disc, which is unlike any other bird. They kind of have a face, more than like a dog or a giraffe. They have this weird, alien face that you can actually make expressive.

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

Twenty years ago my parents wouldn't know who the X-Men were, and now everybody knows that stuff. It means that deconstruction of the superhero is something you can do. All those movies have led to a point where we can finally have 'Watchmen' with a Superman character who doesn't want to save the world and a Batman who has trouble in bed.

I think that, for me, Superman just seemed to make a lot of sense to me. After doing 'Watchmen,' it was - you know that thing, you've got to know the rules before you can break them? There was something about that in making 'Watchmen.'
