Actually, when I did "10,000 B.C.," in the middle of production, I wanted to quit my job, because everything went wrong.

I also, since we have digital cameras, the blue screen composites are so good that I would rather shoot on a stage than there, especially the complicated sequences. The sun never sets in a studio stage.

It's just one of those things. Everybody wants to do it, but it's really difficult. People had to wait for "Indy 4" for a decade, and the reason is because of the people involved.

I was, it was very high. Especially with international (box office), we did something that I didn't think this movie ["2012"] would do. I was very happy.

It's like everybody is obsessed with Hollywood movies worldwide. And even though everybody hates the Americans, they're still watching American movies.

I'm a filmmaker, not a scientist.

I've had the pleasure to work with a lot of very great actors. And they're too different to say who's the best.
