I knew exactly what to do on Alien, it was funny.

I think I was really bored at school. I was quietly clock watching for years. I went to 10 schools because my dad was in the Army and we moved around a lot.

I love different themes, different venues, different movies. I love to jump about and tackle different subjects. I have no intellectual master plan.

I think going into space would be like going deep into the ocean, like 5,000 meters down. When you go down that far, it's just awfully black. There's not much there except mud and some particles. I imagine space would be a similar thing. The only difference is you're hoping to bump into some sort of intelligent extraterritorial being.

You step forward and make it real for a start. You choose a sensible moment in history. Funnily enough, England was bankrupt and the moment is the death of Richard The Lionheart... Richard takes an arrow in the neck collecting a small debt from a small castle on his way home from the Crusades because he's penniless.

Harrison is very much part of this one, but really it’s about finding him; he comes in in the third act.

The time it would take me to write a screenplay it would take me the time to make two films. I would rather make the movies and I'm a better moviemaker than I a would be writer.
