Circle of Iron: Bruce Lee’s Lost Movie

In 1970, a young martial arts instructor embarked upon an ambitious project. His goal: to teach America about the full potential of martial arts, as a vehicle for both physical betterment and spiritual evolution. His name: Bruce Lee.

With the help of two students, actor James Coburn and screenwriter Stirling Silliphant, Lee wrote a script. This unprecedented project, tentatively titled The Silent Flute, would be the first Western movie about martial arts. Against the backdrop of personal combat, the movie would introduce its audience to Eastern concepts of self-mastery. Lee explained his approach in a forward to the script:

The story illustrates a great difference between Oriental and Western thinking. This average Westerner would be intrigued by someone’s ability to catch flies with chopsticks, and would probably say that has nothing to do with how good he is in combat. But the Oriental would realize that a man who has attained such complete mastery of an art reveals his presence of mind in every action. The state of wholeness and imperturbability demonstrated by the master indicated his mastery of self.

And so it is with martial arts. To the Westerner the finger jabs, the side kicks, the back fist, etc., are tools of destruction and violence which is, indeed, one of their functions. But the Oriental believes that the primary function of such tools is revealed when they are self-directed and destroy greed, fear, anger and folly.

Manipulative skill is not the Oriental’s goal. He is aiming his kicks and blows at himself and when successful, may even succeed in knocking himself out…

“Purposelessness,” “empty-mindedness” or “no art” are frequent terms used in the Orient to denote the ultimate achievement of a martial artist. According to Zen, the spirit is by nature formless and no “objects” are to be harbored in it…

True mastery transcends any particular art. It stems from mastery of oneself—the ability, developed through self-discipline, to be calm, fully aware, and completely in tune with oneself and the surroundings. Then, and only then, can a person know himself.

In The Silent Flute, James Coburn would play the role of Cord, a martial artist and seeker of truth. During his journey, Cord would encounter personifications of the obstacles to his enlightenment—form, ego, desire, and death—and ultimately triumph with the assistance of a realized master (to be played by Bruce Lee).

The Big Boss Changes His Mind

Lee and Coburn became frustrated with the project, and with each other, during its pre-production phase. Biographer Tom Bleecker recounts their scouting trip through India and Pakistan:

To begin with, Bruce had taken to giving kung fu demonstrations that would invariably gather large crowds. This bothered Coburn, whose privacy was shattered once he was recognized by the crowd who had congregated around Bruce…

In addition, Bruce had been in the habit of humming pop tunes under his breath and would often do this for hours while the three men were driving through the scorching desert. Finally, Coburn couldn’t take it anymore, and he spun around and shouted at Bruce who was sitting in the back seat, “For Christ’s sake, man, would you cut that out! You’re driving me crazy!” Bruce said nothing, but when Coburn turned back around, he shook his fist at the star’s back in the same manner as he had earlier done at McQueen’s house.

Late that evening the three men checked into a hotel. Bruce felt affronted because Coburn had been given star-preference by the hotel staff, which resulted in Coburn having a more luxurious room. Furious, Bruce went to Stirling to complain that he was supposed to be the star of The Silent Flute, not Coburn, further adding that one day he would be the biggest movie star in the world—bigger than Coburn, whom he now added to his “I’ll-show-you” list just below Steve McQueen!

Coburn dropped out of the project, and Warner Brothers followed. A short time later, Bruce returned to Hong Kong, where his performance in Raymond Chow’s Fist of Fury made him a star.

When Silliphant approached Lee afterwards with the intent of finishing The Silent Flute, Lee declined to participate, reportedly saying “You can’t afford me now.”

Bruce Lee died in 1973, sealing the fate of The Silent Flute. Even if he had lived, however, the film he originally envisioned would never have been made. His script called for subtitled dialogue in Thai, Cantonese, Arabic and Japanese, and featured explicit Tantric sex and extreme violence. In a relatively tame scene on page 9:

A second thug rushes Ah Sahm from the side. Instantly Ah Sahm releases his throat grip, pushes the first thug to his right even as he left side-kicks the rushing second thud in the groin. Before Ah Sahm’s left foot has retouched the earth, he has lept higher and kicked the already groggy first thug in the head, snapping his neck and dropping him lifeless to the ground. The second thug writhes on the ground, doubled in upon himself, his genitals destroyed.

Circle of Iron

Five years later, Bruce Lee’s brainchild was resurrected. The X-rated script was sanitized and adapted by Stanley Mann, who added comic elements to leaven its otherwise austere tone. David Carradine stood in for Lee as the blind teacher Ah Sahm. The Master Yamaguchi character was renamed as Zetan, and the Thailand setting was removed in favor of a fantasy world. Finally, the entire movie was retitled, as the meaningless but imposing Circle of Iron.

Circle of Iron is now available on DVD. The fight choreography is bad, and Jeff Cooper’s acting in the lead role of Cord is worse. Much of its humor is unintentional. Nevertheless, I can recommend it as a fascinating look into Bruce Lee’s philosophy of martial arts.

  1. Hey, i was researching this lost movie you were talking about and i came across this website that has a bunch of stuff about martial arts in the forums and blogs. it quite something. so check it out

  2. Hello there. Thanks for the article!
    Does anybody know where I could find Bruce Lee’s original script for this film?

  3. Yes, a copy of the script is included on the DVD. If you don’t want to buy it, you can rent it.

  4. Yeah i bought the DVD ect last year. Just finished reading the script on the DVD ROM feature. Suprisingly, it was more similar to the movie than i would of thought.

    The fighting in the actually movie that was made was pretty bad. Mainly just Karate moves similar to Carradine in Kung Fu. Still, read between the lines with Bruce Lee’s philosophical mind and the movie is actually pretty cool.
    The movie aint about the moves as such, but the ” fight within”.

  5. THANKS, That was Awesome, It’s kind of creepy that Mr Carradine was layed to rest in Thailand though…

  6. A remake is coming soon, according to Variety:

    Sasha Maslansky, is writing the new screenplay based on Lee’s original treatment.

    “‘The Silent Flute’ will be an epic martial arts adventure film that promises to honor Bruce Lee’s original artistic and philosophical conception,” said Paul Maslansky, who is exec producing. “It also promises to reach new levels of action and adventure never before seen in martial arts filmmaking.”

  7. My Friends –
    You can’t use anything Tom Bleecker says in his “bio” about Bruce Lee as truth. When he was divorced from Bruce Lee’s widow, Linda Lee (now Cadwell), things went south for him quickly; SO, he writes a book of nonsense. How do I know? I was friends with Bruce during that time and up until his death. While he could be tempermental and testy at times andwhile he DID tell Steve that he (Bruce) was going to be the biggest star in the world one day; The Silent Flute was discarded because of (sadly) racism in Hollywood at that time. No-one wanted to spend millions in a film that had a real Chinese man in one of the leads. So in Bruce’s own words:
    “I went back to Hong Kong to make it big there, then come back to Hollywood from the side door, not thefront, but certainly not the back.” And he did become the biggest star in the world after Warner’s “Enter The Dragon,” albiet in death. This fact brought a smile to both Steve McQueen and James Coburn’s faces. They loved Bruce, were his students and two of his pallbearers at his funeral.

  8. Ah, David Carradine, stealing Bruce Lee’s job yet again.

    This time from beyond the grave!

    Meh, I love this film..cheesy and all…it was always on late at night on TV as I stayed up building plastic model kits.

    Good times.

  9. I will revenge for Bruce’s death because i came to know who and how killed him..i’ll revenge i’ll not let the person live anymore..
