I wake up early. At 6:30 A.M., I'm at my most optimistic.

My dad had this philosophy that if you tell children they're beautiful and wonderful then they believe it, and they will be. So I never thought I was unattractive. But I was never one of the girls at school who had lots of boyfriends.

It's quite frightening; the business of trying to be funny is very hairy. In comedy, the potential for humiliation is huge. Trying to be funny and failing is about the most embarrassing thing you can do.

You never in a million years thought that you would ever end up in a Woody Allen film even though that might be your dream, and there you are. Suddenly you've got one. But you're not playing the quintessential Woody Allen heroine, which is somebody that's full of self-doubt and heartbreakingly naïve. Chloe in Match Point was a nightmare in some ways and totally entitled, and felt like everything was going to be all right. Most of the women in Woody Allen films feel like everything's awful. I didn't understand what to do. But some of the confusion is helpful.

In my first few years as an actor, I took one terrible TV job after another. But even as I laughed off my awful roles and made fun of myself to friends, my work made me cringe - I dreaded anyone's seeing it. I was crushed that I wasn't doing anything I was proud of.

I already feel a bit annoyed at myself for writing screenplays. It's a bit, I don't know, model-singer-dancer-actress that went to a posh school. There's something too weirdly predictable about it.

If there's any plan or scheme on my part, it's subconscious. Whatever I do tends to be very different from the thing I did last. You're terrified of boring either yourself or anyone else. It's always attractive if it feels like something that you haven't done before. I generally tend to be better, I think, when I'm terrified out of my wits.
