Trivia: This is the first movie in human history to ever to feature a fully CG (computer generated) character when the knight emerges from the stained glass window. Computer graphics had existed prior (Wrath of Kahn), but never once to simulate an on-screen character.
Trivia: After the credits, Rathe/Eh-Tar checks into an inn under the name "Moriarty." Moriarty is Sherlock Holmes' arch-enemy in the books.
Trivia: The story in the film is not based on any Sherlock Holmes story.
