If there's something I want, I go for it. I just think about how I'm going to go for it.

And the thing is, every time you start a new show or do a new series, you're committing to another six years.

At this age - I'm 44 - I think life's too short. I want it to mean something to me, if I'm going to spend that much time doing it.

There is a danger, if you cast someone who is 18, 19 or 20 to play 14 or 15, that very subtly, almost unconsciously, the audience is, "Oh, this isn't so bad."

When you see Liana [Liberato], who at the time was 14, there is an inexperience and innocence that you can't act and you can't fake.

I think the other honest attraction was that I just grew up loving watching TV and loving watching film, and there's so many directors and actors that I dreamed of working with, I just really wanted to take a crack at it and see if I could ever work with some of those.

If I'm going to do something, I really put everything into it and I want it to mean something to me.
