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 try to put in every one of my movies some sort of message. I don't want to overdo it, because I don't want people to get annoyed by it, but it's good to have a message.

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.

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.

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

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.

A lot of stuff in Wikipedia is not true, and that goes for a lot of people. I sometimes think, "How can that happen?" But Wikipedia is maintained by people, and everybody can add stuff to it.
