History opens up new worlds to film-makers all the time.

I've discovered I've got this preoccupation with ordinary people pursued by large forces.

One of the gratuities about being a director is that you can volunteer yourself out of difficult details.

After a scary movie about the world almost ending, we can walk into the sunlight and say, "Wow, everything's still here. I'm OK!" We like to tease ourselves. Human beings have a need to get close to the edge, and when filmmakers or writers can take them to the edge, it feels like a dream where you're falling, but you wake up just before you hit the ground.

I'm not really interested in making money.

It starts with the writer-it's a familiar dictum, but somehow it keeps getting forgotten along the way. No film-maker, irrespective of his electronic bag of tricks, can ever afford to forget his commitment to the written word.

Science fiction really is the only genre that lets you use your imagination without limitations.
