Circle of Iron is a 1978 martial arts fantasy film directed by Richard Moore and co-written by Bruce Lee, who intended to star in the film himself, but he abandoned the project due to frustration with pre-production and friction with co-stars. The film is also known as The Silent Flute, which was the original title of the story conceived by Lee, James Coburn and Stirling Silliphant in 1969. After Lee's death in 1973, Silliphant and Stanley Mann completed the screenplay, and Lee's part was given to Kung Fu television star David Carradine. Filming began on 28 October 1977 and ended on 20 December 1977. Many other well-known character actors also had small roles in the film, including Roddy McDowall, Eli Wallach and Christopher Lee.
