The Three Musketeers (also known as The Three Musketeers: The Queen's Diamonds) is a 1973 film based on The Three Musketeers by Alexandre Dumas, père. It was directed by Richard Lester and written by George MacDonald Fraser. It was originally proposed in the 1960s as a vehicle for The Beatles, whom Lester had directed in two other films.
The film adheres closely to the novel, but also injects a fair amount of humor. It was shot by David Watkins, with an eye for period detail. The fight scenes were choreographed by master swordsman William Hobbs.
