* AuthorExistenceFailure: Creator/BruceLee scheduled to continue working on the film in September 1973 but he died in July, so the film remained unfinished.
* MissingEpisode: Currently 42 minutes of footage has been found and made public. More scenes might exist in the archives that will probably never be found. A documentary called ''Bruce Lee: A Warrior's Journey'' made in the early 2000's managed to find and piece together as much of the footage as they could find (which includes all of the fight footage from the upper three levels of the pagoda) but also reveals for the first time the movie's original plot, based on Lee's outlines and sketches.
* UrbanLegendOfZelda: Several around this film because it was never finished.
** There are many rumors about more scenes that were filmed (like alleged fights in the car park or at the airport) that are supposedly either destroyed or in the hands of private collectors.
** There are many rumors that the pagoda has more than five floors plus the ground level, and about other fighters Creator/BruceLee meets, like mutants, samurais, dragons, ninjas,... None of these are true.
** There is a persistent rumor that the film is a sequel to ''Film/WayOfTheDragon''. This is disproved by the character names (Hai Tien in Game of Death and Tang Long in Way of the Dragon) and different characterizations of the two (Hai Tien shows much less remorse than Tang Lung)
** Before Lee's death, this would have been a mix between an action movie and a martial arts educational movie. The action side, involved a character named Hai Tien (Played by Lee) Who has to save his sister by giving his captors access to a pagoda they believe houses treasure at the top. The educational side was to showcase the different single styles of Martial arts through each Pagoda Level and how Lee's own Concept of Jeet Kune Do irons out many flaws in said styles. The producers changed to whole plot to a generic revenge story with an evil syndicate.
** Bruce Lee considered several actors, but their scenes were never filmed. These include: Nora Miao, Hwang In-shik, Taky Kimura, Blo Yeung, Betty Ting Pei, Creator/SammoHung, Yuen Biao and Bob Wall. The last three of them appear in the 1978 version, but they don't reprise their intended roles. Other actors that worked together with Bruce Lee, Creator/GeorgeLazenby, Creator/ChuckNorris, Kareem Abdul-Jabbar were offered roles in the 1978 film but turned them down. Only Dan Inosanto reprised his original role.
** From the finalized movie proper, producers initially wanted noted BruceLeeClone "Bruce Li" (real name Ho Chung Tao) to portray Billy Lo in the new footage alongside Kim Tai Chung. Presumably sharing the screen depending on who looked most like Bruce at specific angles. However, Li was three years into his career as a "leading" man and fed up with playing in Brucealike roles (making an exception for numerous biopics where he's obviously an actor playing Bruce and not trying to fool audiences) and turned down the opportunity.
