Sound Effects
Paula Fairfield, the sound designer for “Game of Thrones,” shed some light on the “Big Little Questions” podcast about how the show created the dragons’ noises: by using the sound of tortoises mating.
“The groan of the male actually became, with some work and adjustments, the source for Drogon’s purr with [Daenerys]. The funny thing about the purr with Drogon was watching people watching [the show] and giggling when they heard it, but not really knowing why. To me, it’s because it had that essence, that kind of sensual, sexual essence.”
