In the first earthquake scene [ in "2012"], there was only a limo and a plane. That was it. There was nothing else there, so everything had to be created in the computer, and that's always very difficult.

When it comes to action, I'd say Mel Gibson and Will [Smith] were great.

In the end [of the "2012"], there were no ships, no water, no nothing. Only the interiors [were real]. Everything else had to be made, and that is always challenging.

Everybody knows that the industrialized nations are the worst offenders.

I'm finished with destroying for a while. It's not like I'm running around saying, 'What else can I destroy?'

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

I'm a filmmaker, not a scientist.
