That one [in "2012"] was different because it was all CG, getting washed away by water. In "Independence Day," everything was still done in models, built in a certain scale out of plaster, and packing tons and tons of little explosives and charges in there. We had a second one in case it didn't work the first time, but it worked the first time.

It's very, very rare you find something really original and also because a lot of original stuff, most of the time has no chance, because it's so expensive to make something famous or put it in people's head that it's the one to see, it's like awareness has to be almost like at 80% or 90% if you make an expensive summer movie and that's very hard to do with anything an the White House naturally is in itself some sort of a trademark.

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.

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.

Everybody knows that the industrialized nations are the worst offenders.

Dean [Devlin, Emmerich's partner on "Independence Day"] and I always said that we'd only do it when we had a really good story that excites us both, and we have the story written. And we've had it for a year and a half, two years. So we've been ready.
