Nobody makes movies bad on purpose.

There are shots that I had to walk away from because we had to get the movie in the theaters. There are some in "Independence Day" and "Godzilla," but lately I got smart. I would plan it so I had enough time [to get it right]. That just comes with experience.

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

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.

I've said that "2012" was my favorite ensemble cast, because it was so evenly good.

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.
