I was a huge David Letterman fan, even going back to when he was on NBC. My parents would only let me watch a half hour of television a day, so I would record Letterman the night before and then watch it when I came home from school. That's what made me want to do a T.V. show.

It used to be that in comedy you had to play the clubs and work your way up, but now, before you do the clubs, you can put something up on the Internet. It's public access times a million.

A sketch should be about two to three minutes, which is basically what most songs are. They're usually done by groups. Good examples of each build and have different parts and twists in them. I guess sketch would be the comedy version of music.

I was very young, and I kind of decided I wanted to do comedy. My parents were musicians, so we traveled on a tour bus. You're in a different town every night; as a kid, you're trying to make friends fast. You try to be funny.

I wouldn't say I'm moving to America; I certainly would say that I'm just staying there; and I certainly wouldn't advise anyone to come here unless they've got an extensive CV in the U.K.; you have to build your career wherever you started from.

I'm happy at Real Madrid and can imagine ending my career here - if all goes well.

I know that if I could really understand mental illness, then it would be appropriate to make a big career shift. I would become a therapist and a leader in terms of mental illness. But I'm not in the position.

If I can make a career for myself after Potter, and it goes well, and is varied and with longevity, then that puts to bed the 'child actors argument'.
