  ===Sound===
  Unusual for a television series, the sound team receives a rough cut of a full season and approaches it as a ten-hour feature film. Although seasons one and two had different sound teams, one team has been in charge of sound since then. For the series' blood-and-gore sounds, the team often uses a chamois. For dragon screams, mating tortoises, dolphin, seal, lion and bird sounds have been used.
