I would say, when it comes to comedy, I think Matthew Broderick was great.

We have certain things where we know they exist or "everybody knows they exist," but naturally nobody can photograph them, because they are so super secret. For example, the PEOC, the Presidential Emergency Operations Center exists, but nobody knows how it looks, but it's a so called bunker where he can survive a nuclear attack.

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.

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.

["2012"] it was really more about the subject matter, and to do a modern retelling of Noah's Ark, a flood story.

I always try to convince people that there has to be a lot of material about the subject matter, so they created a couple of pieces. One is about doomsday prophecies.
