The Magic Sword; or, A Medieval Mystery (AKA: Magical Sword) is a 1901 British short silent fantasy film, directed by Walter R. Booth, featuring a mediaeval knight battling to save a damsel from an ogre and a witch. The film, "is impressively elaborate, with single shots containing multiple trick effects achieved through complex double exposures and superimpositions," and according to Michael Brooke of BFI Screenonline, "was so startling that it moved the legendary stage illusionist J.N. Maskelyne (of Maskelyne and Devant fame) to describe The Magic Sword as the finest trick film made up to then."
