I don't regret anything that I've turned down, and I don't regret anything that I've done, really.

It's a very special thing when you go and get to work with your best friend every day.

I'm so thrilled to have been asked to guest in the Doctor Who Christmas Special, I'm such a fan of the show. The read-through was very difficult for me; I wanted to keep stuffing my fingers into my ears and scream 'No spoilers!' Every day on set I’ve had to silence my internal fan-boy squeals!

I am a hard house freak and I don't care who knows.

Eight years ago, I was a waiter, and I didn't have a pot to piss in. And now...? It's like I said to my wife: I love the fact that, if I was in a restaurant and Steven Spielberg walked in, I could go up to him and say, 'Hey, mate, how are you?' I think that's pretty amazing, actually.

People presume just because you're a bigger bloke that you wouldn't be physically fit or up for the fight, but that couldn't be further from the truth.

Someone once pulled me aside and said it was all right to succeed, and I realised that I knew what failure felt like, but I didn't know what success felt like. I've carried that with me ever since.
