If you didn't get it right and then you have to release a director's cut to undo what the studio made you release, I don't know, either it's some marketing thing for them to get more money or the director didn't do his job.

I never really think of something in terms of what not to do. It's always what's appealing or what's cool.

If you don't have something that glues the audience to the screen, you're in trouble.

I grew up as an artist. Science fiction allows for design and creatures and guns and all the stuff that I like as well. So I think most of the films I make, I'm sure, will be in that category. But I can also see myself making a film like 'Black Hawk Down,' and I could also totally do horror.

There are loads of sociopolitical, racial, class and future-planet situations that really interest me, but I'm not really interested in making a film about them in a film that feels like reality because people view that in a different way. I like using science fiction to talk about subjects through the veneer of science fiction.

If it takes several billion years to develop the building blocks which you need, like RNA and DNA, and then those can build multicellular life and then multicellular life can be honed with natural selection to a point where it becomes sentient like us, then at some point that sentient being can begin to manipulate the matter around it to build better sentient life.

You can build a brain the size of a room, theoretically. You could also build a silicone based life form and it could be sentient. There's no limit to the height that you can reach in terms of design once we figure out how to design things, theoretically.
