With John Wayne Gacy - the serial killer who dressed up as a clown - there's just something about clowns I don't trust. I don't think they're particularly funny. They're a little spooky. Not my sense of humor, I don't laugh at clowns.

There was a courtroom scene where my son is convicted of killing Kevin Spacey's character. I find the bloody T-shirt and realize my husband did it. I get up the courage to take the shirt and send it to the police as evidence. I go out of the house for the first time. There was all this stuff I had to do that became quite truncated, because they slimmed down the movie. I understand the American Beauty is brilliant without all that stuff, but for me, personally, it was hard to see all that go.

I can access emotions very easily.

I guess my height has hurt me as much as it's helped me. In comedy people don't mind casting tall women next to shorter men. It adds to the humour.

Comedy is a serious business. It's frustrating when I can't find the right thing that makes the crew laugh. If I don't make them laugh, I get very disappointed in myself. You don't really have a live audience, so you just depend on the crew to let you know if you're doing something funny.

I never stop. I don't want to stop acting because I'm afraid it'll all end, so I never say no.

It's a challenge for me to make people like me. Maybe it's just my desperate need for people to like me, that I choose the characters I have to play. You will like me, I don't care what I've done, you're going to like me.
