Unrelated, but my favorite story about Jurassic Park was that when they were filming the T-rex attack scenes, they had to try and keep the robot dry or it would start malfunctioning. So they had it in a hanger drying out and part of the malfunction was that it would….start to move…on its own. Shorts in the wiring or whatever. Now, only about half the crew knew this, and they neglected to inform everyone else so someone would be filming a ‘behind the scenes’ interview with a crew member when out of nowhere would come a chorus of utterly horrified screaming and running followed by unholy giggles from whoever put two and two together and realized that the T-rex had “come alive” again.
But really, how awesome is that, that you can make a puppet that everyone knows isn’t real, has been dead for 65 million years on, have it standing in a workshop with wires and crap sticking out the back end and still have it terrify the shit out of people?
