I think everyone's a geek in some way.

When I was at college, I worked in a department store called Brit Home Stores, which is a pretty lackluster department store, selling clothes for middle-aged women. My job was to walk the floor and find anything that was damaged, take it to the store room and log it.

I have a natural curiosity about things, in general. I'm constantly trying to find out how things work and how I can put them back together again, and why they work that way. The natural world is all around us.

If I had a choice as to my perfect career, I would make a couple of films a year and then concentrate on natural history.

I can easily say "no" to a project if the script isn't great, but when the script is good, then I start asking the other questions. Who's going to direct it? Who's the creator? Who are the actors? When are we shooting? Where is it shooting? All that kind of stuff.

If I could uninvent anything, I would uninvent Hitler's mum, guns and broccoli.

I think we are all interested in end-times ideas and also in the current climate that we are all living in, where money is a little harder to come by, things continue to get expensive; gas prices are not too far from people's heads. There are more and more people. Human society's going to have real problems.
