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!

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.

I'm not good at meeting people, and I'm not good at small talk.

Even though I didn't write 'Shaun Of The Dead' and 'Hot Fuzz,' I never felt left out of the creative process.

One of my biggest disappointments is watching the trailer for the second Lord of the Rings film and having Gandalf in it. Why? He died in the first one, why give it away in the trailer just to try and sell 1000 more seats? It's daft.

I was an amazing bartender and a great waiter. I think, in a way, that was my acting school.

I would agree Paul is a sci-fi genre movie. And a road movie.
