20 Mind-Blowing Facts About The Jurassic Park Franchise
9. Mating Animals Provided Some Of The Most Crucial Sound Effects
Fortunately Steven Spielbergs services werent required for the essential task of giving the dinosaurs their voices in post-production; that job fell to sound designer Gary Rydstrom, and some of his choices and methods were unusual. Rydstrom needed to create dozens of distinct sounds for the film's various species and went to great lengths to stockpile some very specific audio. The noises made by the T. rex when it shakes a raptor/Gallimimus/lawyer in its jaws came from Rydstroms own Jack Russell terrier Buster playing with a rope toy, and geese, donkeys, baby elephants, cows, swans and horses in heat were all utilised in sound design that would garner two Oscars. As for the sounds the raptors made to communicate with one another, well, those came from an exceedingly unlikely source:
It's somewhat embarrassing, but when the raptors bark at each other to communicate, it's a tortoise having sex. It's a mating tortoise! I recorded that at Marine World; the people there said, Would you like to record these two tortoises that are mating? It sounded like a joke, because tortoises mating can take a long time. You've got to have plenty of time to sit around and watch and record them.
I watch movies and I watch sport. I also watch movies about sport, and if there were a sport about movies I'd watch that too. The internet was the closest thing I could find.
