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.

I spent about a year and a half doing technical post work on 'The Fountain'. Although I do like the process, I think my favorite part of filmmaking is the actors.

The whole visual language of the movie is developed way before we get to set. Especially when you're doing visual effects and you don't have a lot of money to mess around, which we didn't, you have to really preplan everything. Pretty much every shot in the film was figured out months before we got to set.

I think there's something in collaboration - the fact that you can sit there and bounce ideas off of someone. It definitely matters who the person is, because certain people... The act of collaboration, where you can talk to someone, hang out, get ideas going, there is something in that. That's similar between everyone. But I think every individual collaborator is different, because they have different brains and emotions and ways of working, so it changes. Definitely.

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.

I think it's my nature to try and make original content, and that's what I've done, is just try and approach things in an original way, and do things differently.
