As an actor I can sort of smell a duff note, that isn't full of that much conviction. My worst thing with directors is when I know more than them about the character.

At university I had a big coloured scarf and people would often say, 'All right, Doctor Who?' And, I thought, I rather liked that notion.

I think you can hear the struggles and hear a realness in Theocracy songs, a human element that you don't get from a lot of the typical Christian stuff.

I think that every artistic venture is a risk, and it has to be that way, so you do as much preparation as you can and make that as thorough as you can possibly make it, until you turn up on set. It's about taking risks, and some might work and some might not, but that's what makes it interesting.

It seems like there's a real appetite for science fiction in the States.

I think there are definite parallels between sport and art. There's a real sense of sacrifice. There's a real sense of dedication that is needed in sport that I think you can attribute to art. I think so much of it is about bravery and courage, being an actor.

Even now, I'm very superstitious, in silly ways. I always put my left boot on first. Or on set, I always tie my bow tie from right to left.
