Santa Claus: The Movie

Santa Claus: The Movie was a film about Santa Claus (played by Dudley Moore) which also featured Santa's elves. It was a "guilty pleasure" of Shona McCullough, who had rewatched it shortly before being bit by a dream crab and entering a shared dream-state also including the Twelfth Doctor and Clara Oswald. This led to the appearance of Ian the Elf in the dream. (PROSE: Ian the Elf)
