The Three Musketeers is a 1933 film serial produced by Mascot Pictures which updates Dumas' The Three Musketeers by setting the story in contemporary North Africa. The Musketeers are soldiers in the French Foreign Legion, and D'Artagnan (renamed Lt. Tom Wayne and played by John Wayne), is a pilot in the United States military. The supporting cast features Raymond Hatton, Francis X. Bushman, Jr., Lon Chaney, Jr. and Noah Beery, Jr..

When Lt. Wayne is framed for the murder of his fiancée's brother, Armand Corday (Lon Chaney, Jr., credited in this movie as Creighton Cheney), he vows to capture the real killer, a mysterious Arab terrorist known only as El Shaitan. He is aided by the Three Musketeers: Clancy (an Irishman always spoiling for a fight), Renard, and Schmidt (who loves sausages). Nicknamed the "Devil of the Desert", El Shaitan leads a desert cult and a secret society against the French Foreign Legion. He remains a shadowy figure, hiding his face and his true identity, as a result of which many people are mistakenly suspected of being El Shaitan, while other characters impersonate him for their own ends.
