Behind the scenes
This species' name was never spelled on-screen, allowing for closed captioning to determine proper spelling. Unfortunately, there was discrepancy amongst closed captioners. Those working for ABC and BBCA went with Lugaleracush, while the official BBC One captioning done by Red Bee Media had it as Lugalirakush (TV: The Rings of Akhaten on DVD) or Lugal-Irra-Kush(on iPlayer?).
