Clangers

Clangers was a popular children's TV show broadcast in Britain during the 1970s. It was made using stop motion animation, and was directed by Oliver Postgate and Peter Firmin.

The Master watched an episode of Clangers while he was imprisoned by UNIT (specifically, the episode "The Intruder"), he whistled along with the noises they made. He joked to George Trenchard that they "seem to be a rather interesting extraterrestrial lifeform". Trenchard, believing the Master really thought the Clangers were aliens, told him it was just a puppet show. The Master showed visible frustration with the man behind his back. (DW: The Sea Devils)

Behind the scenes

 * The Clangers scene was a last minute addition, as the episode was 90 seconds short of the typical run time.
