Although computer chips now are thinner, they're more powerful, they're not as reliable. You'd harvest computer chips from the 1980s from all around the world because they're reliable.

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.

It's interesting, the worse things get in cities, the tougher that cities get, the more brutal the humor is. The tougher things people face, the darker the sense of humor gets and I find that incredibly optimistic.

Good storytelling for me is not so much technical expertise, which I know is applauded often; it's actually freshness of approach. It does mean you sometimes stumble and fall and make a horrible mess of things in seeking that freshness, but you should always keep trying to do that.

You can't tell someone they are wrong about their own life.

Once, a French journalist told me that all my films are the same. I said, 'Excuse me? I work hard to make them different.' What she meant was that in my films there is a character that faces insurmountable odds, and they overcome them. But I thought that might be true, but you need certain factors for drama, and you need to overcome them.

We want to see drama told in a cathartic way, with power, with emotion where you empathize and then you're frightened. All those feelings charge up in you and you feel for the story.
