If you want to assemble the same people, then you have a big problem.

The President of the United States has super star status. He's not a normal person, because he's protected like no other person in the world and if this man's life is in danger, the whole world is kind of in peril in a way, because the leader of the free world could fall into the hands of terrorists.

I think every good, entertaining movie should have a message. I really believe that, because if you do it without it, the film feels a little bit soulless.

I think sport in general affects what people see in movies. I always try to explain to people in Hollywood that we have to make movies more like sport because, in sport, everything can happen and it's so much better than movies in some ways.

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.

There's not really much destruction in New York besides the weather and it's a natural force so it's not like any destruction. But LA gets leveled (laughs). That's my comment to Hollywood.

I'm a filmmaker, not a scientist.
