The Game of Death is an incomplete 1972 Hong Kong martial arts film directed, written, produced by and starring Bruce Lee, in his final film attempt. Lee died during the making of the film. Over 100 minutes of footage was shot prior to his death, some of which was later misplaced in the Golden Harvest archives. The remaining footage has been released with Lee's original Cantonese and English dialogue, with John Little dubbing Lee's Hai Tien character as part of the documentary entitled Bruce Lee:

The film was successful at the Hong Kong box office, grossing HK$3,436,169, but was not well received. Criticism of the revised version included the inclusion of scenes that could be considered in bad taste, such as the incorporation of footage of Lee's actual funeral. Another scene, often pointed out by critics of the film, involved a shot of Kim looking at himself in the mirror, with an obvious cardboard cut-out of Lee's face pasted onto the mirror's surface.  The action directed by Sammo Hung for the scenes with the Bruce Lee lookalikes and the footage that Lee shot for the original footage with the final three fights helped to alleviate the movie's problems. Apart from the cheesy techniques used to disguise the fact that Lee was being played by stand-ins, the movie enjoyed respectable production values.  Bey Logan points out a few logic issues with the 1978 film. In order for the henchmen to remain low key, they should be wearing more casual clothes instead of the multicolored tracksuits seen at various parts of the film. But as a rationale, this explains why Lee wears the yellow tracksuit. Also in the fight between Lee and Kareem Abdul-Jabbar, the scene near the vase in Logan's opinion appears to look choppy along with the short fight with Hugh O'Brian. Perhaps the most important thing on the first half of the English version, Lee's fight sequence has been taken down to a more realistic level and unlike previous films, he is seen to be beaten down instead of making short work of these henchmen.  However, despite those major flaws, for the western audiences, the story narrative is easier to follow through compared to his earlier films like The Big Boss, Fist of Fury and Way of the Dragon. Compared to the Hong Kong films, it has western characters and the story structure is more straightforward than the Hong Kong structure which has action, but the story's humor and drama might not work for the people in the west like the US and the UK.  Review aggregator Rotten Tomatoes reports the film as holding an overall 75% approval rating based on 8 reviews, of these six were fresh and two were rotten.
