Noah is the battle of justice versus mercy. In Genesis it says that Noah was righteous in his times. You think you sort of know what righteous means, you know, if you listen to a lot of Bob Marley. According to all the biblical scholars we talked to, righteousness is the proper balance of justice and mercy. If you think of that, as a parent, you know that if you have too much justice and you're too strict, you destroy a child. If you have too much mercy, as a parent, you destroy a child as well. A big part of this movie is Noah finding mercy for man.

When people think about the ark, they're always thinking about all the thousands of years of religious iconography of a ship with a bow and a deck, where Noah and the giraffes could walk around. In the actual written text it is basically described as a long, rectangular box.

Comic books and graphic novels are a great medium. It's incredibly underused.

I've been joking that if Madonna taught us anything, you've got to reinvent yourself. I think it's important as a filmmaker, as any person working in the arts, that you've got to try new stuff and challenge yourself and take chances. I've tried to take a chance with every film I've done - I've never done it the easy way, and I think that's because that's what excites me, is making as big a mountain as I can in front of me, and just trying to mount it.

I think video games and that stuff should be as violent as possible, but age-appropriate. It should be realistic. When it's not realistic you run into kids running around shooting people and not realizing the consequences.

Casting ethnic characters is a very hard thing to do, but it's important. It's also interesting.

Unfortunately, when you're working in film, it's this huge machine, and you've got to get everyone right there, so you get kind of locked into things. I'm not sure where the artistry in film making is. It's usually that moment when you're on set and you're working with the actors. That's the time to play around, the moment of theater. And then you can shape things. But a lot of it is just managing stuff. It's upsetting because you get away from the core.
