The great thing about space films generally, with the exception of Apollo 13, is that big stars tend not to work in space and I think that's because space is an equaliser. It makes everyone the same really and suits an ensemble cast and actors who are prepared to work with each other.

To be a film-maker, you have to lead. You have to be psychotic in your desire to do something. People always like the easy route. You have to push very hard to get something unusual, something different.

You can do anything you like - really - but this Sci-Fi is absolutely disciplined, it's Zen, you have to be absolutely focused in an area. You have to zone into an area and you then you can achieve when you get there. It's really weird!

The great thing with film is that it doesn't have an ego. It's just a film. Everybody that makes them has an ego, and the problem with awards and stuff like that is that it always affects the egos, and everyone gets stained by it in some way. And that can be fine and very innocent, but it can be horrible as well.

Clearly, you can think back and see that a character has had enormous odds stacked against him and has to overcome them. It's usually a guy, I'm afraid. But then you're setting up a new movie you have amnesia about these meetings, when you've discussed it more analytically.

People say you never remember anybody who dies in movies, and it's true, you don't. You don't even remember people who disappear. Although the moment that it happens might be terribly sad and moving, five minutes later, if you're asked to remember that person, you go, "Oh right, yeah, yeah!" 'Cause you're just moving forward.

My kids are too old to remember this now but, when they were much younger, I swore to them if this miracle ever happened, I would receive it in the spirit of Tigger from Winnie the Pooh, and thats what that was.
