Continuity mistake: During the fight scene with Oharra, Bruce Lee was actually cut quite badly on the hand. In later scenes in the film he can actually be seen with a bandage round the injured hand.
Continuity mistake: During the fight scene in the mirror room, Lee starts to punch and kick the mirrors. During several shots, Lee is wearing shoes that fully cover the top of his foot. In others, he is wearing a pair of shoes that have a V cut down the top of his foot which you can clearly see with his white socks.
Continuity mistake: Someone got a little makeup happy. In Han's office, Williams beats up a few guards and then Han takes things into his own hands (or hand as it turns out.) As they fight, there is a shot of Williams head-on just before Han hits his birdcage. Williams has a bruise under his eye. But why? Han hasn't hit him yet and neither did any of the guards. Nor was he hit in the face during his match with Parsons earlier in the film. I suppose it could be a shadow but it doesn't look like it.
Continuity mistake: Near the end of the film, Roper knocks out Bolo, Han's right-hand man. But when we see Han sending his men after Lee and Roper in the next wide shot, Bolo's body is nowhere to be seen. (01:28:40)
Continuity mistake: When Bruce has the battle underground he has black socks on, but when he is captured and they show him being untied outside he has white socks on.
Continuity mistake: When they're fighting in the mirror place, Bruce gets slashed on the face. The space between the cuts is narrower than the cuts he gets from the same claw when he gets slashed on the belly.
Continuity mistake: In the banquet sequence, John Saxon is shown sitting with a glass in his hand. The level of liquid in the glass fluctuates alarmingly from shot to shot.
Continuity mistake: During the fight scene near the end of the film between Han's white clad henchmen and the black dressed good guys, there is a shot of a guy spin kicking another that is shown 3 times. Many other shots are shown more than once, from close up or a slightly different angle.
Continuity mistake: During the flashback with Su Lin: Just after she starts running away from her attackers she trips and falls on a patch of dirt. Everything around is concrete and that patch is the only dirt visible. Isn't it lucky she had something soft to land on?
Continuity mistake: Approximately 14 minutes into the film, Bruce Lee's sister kicks a guy in the groin. He then goes on to fall twice.
Continuity mistake: During the scene where we see Bruce Lee's sister being harassed by a group of men, at one point she kicks a man in the groin, he starts to fall and she turns around. Then the angle changes and again she turns around as the man falls.
Continuity mistake: Parsons is fighting Williams. There's no bruise on Parsons' face to begin with. He falls with his back to the floor, and magically develops a bruise on his face after he gets up.
Continuity mistake: After Bruce has scared the radio controllers from their booth with the cobra we see him calmly resting his palm on his cheek. Cut to another shot of the radio guys splitting and his palm is more at his temple. The shot goes back to him and it's on his cheek again.
Continuity mistake: Just before Roper fights Bolo there is a shot of Bruce backing away with his arms at his sides, then the shot changes to a POV from Bolo and instantly Bruce now has his arms folded.
Continuity mistake: Near the end of the movie Bruce Lee fights underground with a track suit bottom type trousers. He is then captured, and in the next scene he is wearing baggy flared tracksuit trousers.
Continuity mistake: At the beginning of the end fight scene between Lee and Han, Han has a black glove on his right hand. We then see a few shots of his hand with no glove on, and then it returns again for the rest of the scene.
Continuity mistake: In the fight with O'Hara, Lee sidekicks O'Hara and sends him flying over backwards into the crowd. The brown bottle is left standing upright. When they cut back to O'Hara now reaching for the bottle, suddenly it's on it's side spilling the contents. (01:20:00)
Continuity mistake: When Bruce Lee and Han first jump up at one another, Han slashes Lee across the stomach with his 4-knife hand, but Lee only has 3 blood scars across his abs for the rest of the film.
Answer: Yes, he filmed all of his scenes before he died. He died on July 20, 1973 - only six days before the film debuted in Hong Kong, and only a month before the film's US debut.
