I don't make films that are easy to market, unfortunately. I think that 'Pi' was the easiest one, because we had that symbol to stick up everywhere, so that was a good gimmick, and created a good mystery, and we didn't have to do huge scale.

I feel that so many sci-fi films and films in general have just become really dependent on and addicted to CGI, and that some of the big CGI films of the summer, you see these effects that look like crap. You don't know if you're watching a cartoon or something that's real. And I didn't want to fall into that trap. I really thought there was a way to use a lot of these old techniques to do some new and really neat stuff.

I remember the few times that happened to me in writing, where you basically start writing and you look at the clock and six hours have gone by and you're, like, "Whoa! What the hell just happened?" And that piece ends up in the final product even though the final product is three years away. It doesn't get rewritten. It came out the right way. But that's happened to me so few times in my life.

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

Artist and illustrator R. Crumb did a whole illustration of Genesis. And he didn't go away from the text; he was totally truthful. Reading through that, I was like, "Oh, wow, it's a comic-book version of the Bible." There's a lot of heavy-duty stuff that goes on that doesn't make it into Sunday school.

Turning 30 was when my parents both got cancer and were fighting it and beat it, but their mortality started to get to me. Everything wasn't as hunky-dory like it was.

At the end of Requiem all I wanted to do was get a DV camera and just do a small film. But then the hunger comes back.
