Part of making the Jurassic Park franchise’s dinosaurs awe-inspiring is the sound design, and Jurassic World had to introduce the roars of a few new dinosaurs. In this video, the movie’s sound designers explain what animals went into Mosasaurus and Apatosaurus voices, and how the Indominus got that horrific screeching.

SoundWorks Collection interviewed Sound Designer and Re-recording Mixer Pete Horner and Supervising Sound Editor and Sound Designer Al Nelson from Skywalker Sound about their work on Jurassic World. It’s particularly appropriate that such a mishmash of animal noises when into the mutant Indominus. It’s stuff like this that made the movie so much fun to watch, even if we had many, many issues with the story.
