The eerie sounds made by the dinosaurs in the film were actually recordings of real animals… but how many can you identify from the clip?
The creepy hisses are actually recordings of geese and the velociraptor’s heavy breathing is from a horse. But the communicative barks are much more difficult to identify. The sound director himself, Gary Rydstrom, revealed that he recorded those bone-chilling sounds at Marine World in California while tortoises were mating. That’s right, the most terrifying sound of the 1990s is, in fact, a pair of giant tortoises.
The hit 1993 film Jurassic Park is due to be followed up by a fourth instalment on 12 June 2015.
