Continuity mistake: Watch the bar scene about ten minutes from the start of the film. The barmaid is holding 2 pints, but note how the froth disappears when the shot changes as they are placed on the bar.
Continuity mistake: When Mr Bernard pulls Miss Banks' dress he throws it behind her. When she runs to her office she is holding the dress in her hand.
Continuity mistake: The protagonist is weilding his karate skills against the crooked cops in the final fight scene. One of his foes is wearing a white fishing cap. Superfly belts him and knocks of the cap, there is a cut and then the cap is on again. The cap is on and then off again twice more in the same fight scene.
Continuity mistake: After Bruce Lee kills Chuck Norris, he walks back and picks up Chucks Gi and Obi (karate shirt and karate belt). The belt is hanging and dragging on the floor but as Bruce walks from behind a column, the Obi appears to be folded properly.
Continuity mistake: At the end of the film when Oliver Reed is in the Range Rover and ramming the Hillman Avenger, watch the number plate of the Avenger. It switches repeatedly between a 'K' suffix and a 'J'.
Continuity mistake: When Weasel and Sadie are chasing Phyllis through the woods, Sadie takes off her jacket and throws it on the ground. It later reappears and then disappears again.
Continuity mistake: When Captain Bollin is questioning Shaft in his office, his hand position between shots is not always consistent. Best example when he asks Shaft about Mascola: he is leaning with his left hand on the top of the file cabinet, but he's shown rubbing his hands together in the following shot. (00:29:40)
Continuity mistake: When T and Texas Blood are playing pool, the balls would move around after the stopped. Most notably after T makes the 1-ball. The cue ball is on the opposite side of the dot than the 8-ball and the other two balls are on the other end. In the next shot, the cue ball is on the same side as the 8-ball and the other two balls are now close to the cue ball.
Continuity mistake: At the beginning of the movie, Bruce Lee enters a restaurant in the Rome airport and, because he can't read the menu nor speak the language, he accidentally orders five bowls of Campbell's Soup. When the waitress first delivers the five bowls, the soups are very different colors than they are in subsequent close-ups. Disappointed but hungry, Bruce plows into the soup. Ten sequential close-up shots show him dipping his spoon into bright red, tomato-based soups; but, by the time the spoon reaches his mouth, the spoon is dripping creamy white soup, every time.
