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.
