My scripts are always heavily noted. If I can take a director to one side and say, "Do you mind if we try this?," a few days before, that's usually a better way of doing it then on the 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!

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

I find acting tough, but sitting around chatting - that's easy.

If you think about America, it is about getting your backpack on and heading out.

I am a geek in terms of, I love 'Close Encounters' and I love 'Star Wars,' but other things... 'Doctor Who,' I don't really care about at all, I couldn't give a fig about it.

My formative years were all about 'Star Wars' - the first three, not the last crap, obviously. I understood 'Star Trek' but it was too caricatured for me.
