There's nothing so unattractive as vanity... particularly male vanity.

I never mind talking about my dad. I'm proud of who he is, and being his son is one of the things I'm most proud of. To be constantly compared to someone so brilliant, who happens to be your dad, is cool.

When you do a film, you get picked up in a car, lunch is free. Theatre is really hard, and you get absolutely no money.

My mum and dad have always enjoyed life, and it's something that's been instilled in me. I wake up in a good mood most mornings.

I've done loads of things people have never seen, dramas on BBC4 and plays upstairs at the Royal Court and the Bush, and because I didn't go to drama school, they gave me an education.

You do stuff that gets a reaction and you think 'that's a winner' and then it never sees the light of day. But the thing with improvisation is that 90% of what you come up with won't be used and for good reason. But you keep going for the occasional gem that you might come up with. You do a scene and a lot of the time. We wouldn't cut. So, you come up with something that might be funny and then you go, 'alright, what else'? So, you kind of throw stuff against the wall and see what happens. But you've got to be prepared to make a fool of yourself.

Because I was always a fat child, I got fatter and fatter, and I ended up 18 stone and with a 40-inch waist.
