If I had cast someone else who didn't have that kind of timing, it would have been leaden and one note. But Ann [Morgan Guilbert] made her really human and really funny without being caricatured or over the top. She feels like a real person.

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 have a boundary problem... I need to know when to give and when to back up. I'll help someone across the street and then into their homes and they'll start telling me all their problems... and it turns out they're insane and want to kill me. I've got to know when to stop!

Filming is a funny combination of having a good time and not being able to wait until its over.

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.

Hollywood always likes to create a star.
