Marriages are so complicated that no one person is the culprit. But, I am really interested in class without really realizing that I am. It's more the manifestations of different classes that interest me.

But then male directors also have a hard time getting their movies made... not as hard as women but it's a tough time for any movie this size. And that particular movie [The Hurt Locker] was so specific. It couldn't hurt, of course, and I'm really glad for her, but I don't know how much it will change things, if at all. The film industry is still so sexist.

I thought I could make a sarcastic joke about it. But it's based on my own struggle with how much to give, how much it's really helping or not, and how foolish or not I feel. Giving sometimes backfires.

It seemed like there were so many options in filmmaking before. If they don't want to make it, well okay, there's a hundred other places we can try. I'm not a producer and I don't even know the places my producer goes to, thankfully. But I think there are far fewer options now to releasing a movie theatrically or to getting the financing.

I guess I always knew going into the movie that casting that part would be difficult. Oliver just felt likeable. I felt it would be hard to dislike this man. I don't know why, but I'm sure other directors have felt the same when casting him. Oliver is goofy yet formidable, smart but likeable... I didn't want the character of Alex to be nasty or demonised. I wanted him to be struggling with his actions.

I thought of the scene while writing scenes with Rebecca [Hall] and wrote it like an opening montage of showing where someone works. If you see a film about a car mechanic, you'd show the place they work and what they do. So, that's what I set out to do with Rebecca's character. I thought it probably wouldn't even make it into film but I ended up liking it.

People say to me all the time that I threw some money into some guy's coffee cup [by accident, thinking they were poor]. People do make the same sort of mistake. I've made attempts to volunteer that have been calamitous!
