Trivia: Enter the Dragon

  • Executive Meddling:
    • In the original script, Roper dies and Williams survives. This was reversed by John Saxon's agent to land him a bigger part; it was not an example of racist executives.
    • Lee, playing a secret agent, wanted to use a gun in at least one scene. See Why Don't You Just Shoot Him? on the main page.
  • The Danza:
    • Lee, played by Bruce Lee.
    • In an inversion, actor Yang Zse took the stage name of Bolo Yeung to cash in on his sudden exposure in this film as the villainous Bolo.
  • Hey, It's That Guy! -
    • One of the thugs that assaults Roper on the golf course is Pat E. Johnson, a student of Chuck Norris best known as the referee from The Karate Kid.
    • Jackie Chan is a Mook who gets his neck snapped by Bruce Lee. Considering his age at the time and the fact that he's an extra, it is difficult to tell. It's easier to spot once you know when it occurs (it happens as Lee infiltrates the lab, and is the only Neck Snap to occur during that scene)
    • Tony Liu, who played Hsiao Chiun, the boss' son in The Big Boss, and had roles in the other two Lee Hong Kong films, plays a combatant who at first gives Roper a run for his money.
    • Lao Che is Lee's master at the Shaolin Temple.
    • The Big Bad from Bloodsport practically plays the same character but as The Dragon. This one is easy to notice since he apparently didn't age between 1973 and 1988.
    • Sammo Hung is Lee's sparring partner in the opening scene.
    • Roper would help kill a child murderer that would come back from the dead and get revenge by terrorizing the dreams of his daughter.
  • Looping Lines: The entire movie was filmed without sound, and so virtually all the actors had to loop their dialogue after filming was complete, with a couple of exceptions:
    • Kien Shih (Han) spoke no English, so his voice was dubbed by Chinese-American actor Keye Luke.
    • When the extended Cantonese/Mandarin versions were released for the first time in English in 1998, some extra dubbing had to be done, because no English dialogue existed at that time for those scenes. One of the scenes involved Roy Chiao (Shaolin Abbott) and Bruce Lee. Chiao was still alive (he died shortly thereafter), and was able to dub himself, but Lee's voice was supplied by Bruce Lee biographer John Little. Luckily, Lee's real voice was left alone for the scenes that originally used it.
  • Unintentional Period Piece: The leisure suits, turtle necks, the funky music, Williams' afro and manner of speech along with mentioning that the Vietnam War was only a few years ago, all point to this movie being in The '70s. Also, this movie is mostly responsible for kick-starting the kung-fu craze in the US during this time.
