It's something that I am going over in my head about the whole video game thing, and whether you support violence by being in a film like this. I mean, to me, it's incredibly unreal and it's all about the action, and just explosions.

In the original computer game of Doom, you not only have to kill things. You have to pulverise them.

Acting is about communicating what it is like to be human: the pain, the laughs, the misery, the joy. I suppose I am searching to have it all.

Nothing can teach you what it's like to work on a film set, and the best education there can be for an actor is to walk up the street and observe human nature.

It was in New York, and I've always wanted to film in New York. And the writer was a teenage friend of mine. We did youth theatre together when we were 16 and always had a dream of making a film together. And ten years later, we've done it. So it's great.

I know I’ve got loads that has never been tapped.

I've got friends who are pyrotechnics who do big fire shows, so I'm really fascinated by that.
