Continuity mistake: Jason beats the 4 slobs outside of the bar and sends them away running. The shadow of the parked trailer changes angle between shots as he walks back to his dad. (01:09:25)
Revealing mistake: Jason charges in to save his dad from the beating. He breezes past the three goons and the last to charge him is the drunk dude that caused the whole commotion. In the middle shot that follows it's blatant that the exchange starts with the guy on his feet, standing, and not running at Jason, and there are visible pauses between the punches where he is waiting to be counterpunched. Completely open and still. (01:08:50)
Continuity mistake: When Karate Man is attacked by Coca Cola shirt, Fat Guy with a Mullet grabs him from behind. His right arm is above the aggressor's, but in the next shot it's into his clutch. (01:08:15)
Continuity mistake: Karate Man is surrounded by a bunch of awfully looking guys in the parking lot. The dude with the sponsor's shirt begins to attack him charging his right fist. Next shot and attacks with a left hook. (01:08:15)
Other mistake: When by extraordinary luck Jason's mum can't go pick up dad exactly the day that he has to fight off a bunch of thugs, notice on the front of the car the fake Washington state license plate about to come off. (01:07:10)
Other mistake: Jason's reaction when he sees Bruce Lee walk back into the light is just silly. He perfectly sees him walk away, but he looks left and right and springing on his toes as if he were trying to look past an obstacle. Not investigate a doorway. (01:04:25)
Continuity mistake: Jason finally kicks the suspended bag. He frees his foot from the noose, but he's in a different position and different is the height his leg is at and the band that tightens the noose. Even the photography and/or lighting, for no reason. (01:03:55)
Continuity mistake: Sensei Lee tells Jason some mumbo-jumbo about seeing the impossible to make it happen. When he says "And know it can't be stopped" the light of the scene is different, going more or less from night to day. (01:03:45)
Other mistake: Jason's dad is still limping heavily and barely makes it to the pool table to bring the beer. 20 seconds later he's dragging an angry and non-cooperative guy bigger than he is all across the beer joint, and even tosses him out of the door as he lands with a nice graceful flip like of course any drunk dudes would. (01:03:15)
Continuity mistake: When Tom Stillwell is being harassed by what looks like an overgrown Scott, the wet spot on his shirt and the messy hair on his forehead change as he walks away. (01:03:00)
Continuity mistake: At the bar where Jason's dad is working, the establishing shot shows already the drunk guy downing a drink, with the billiard balls set up in the traditional triangular shape that leads to the break shot. When we actually see the break shot though, the balls are not in the same formation. For instance, the green ball was the third one from the left in the bottom row, and it's the corner left in the overhead shot. (01:03:25)
Audio problem: During the training to defeat the champion from Soviet Russia, Bruce Lee says "This time I'll kick YOU", but the phrase is out of synch. (01:00:05)
Continuity mistake: In his training with Sensei Lee, at one point he grabs Jason's leg in the air and asks him "what now?" Between shots Tae-jeong Kim 's hand gets further away from the knee, and Kurt McKinney's that was holding the leg itself is now on Lee's finger-pointing hand. (01:00:00)
Continuity mistake: The patch of sweat on Jason's shirt gets bigger (from above to below the pecs) in the short walk from the training machine to the wooden dummy. (00:55:35)
Continuity mistake: The ghost of Bruce Lee one-inch-punches Jason; he falls against the wall with his tie dropping between his arm and the body, but in the next shot the tie is on the outside of the arm. (00:53:25)
Continuity mistake: When Bruce Lee writes on the wall a Chinese character, the hand in close-up is casting a shadow towards the right, and in the shot with the actual actors the shadow is on the left. (00:50:10)
Continuity mistake: When Jason stares for the first time at "sensei Lee" (who does not look like Bruce Lee, who not being japanese can hardly be called a 'sensei'), his posture is different between shots, and so is the shadow that the 'ghost' casts on him. (00:49:25)
Continuity mistake: RJ and Jason have just dumped all the garage junk in the conveniently spare uninhabited house the kid happens to know of. When Jason says "You go ahead, RJ" they are both suddenly sitting in different positions than before. (00:46:30)
Continuity mistake: When Jason is kneeling by the tomb begging the dead corpse of Bruce Lee to help him deal with the bullies (like any normal, not insane person would), he is gripping the corner of the monument's base in one shot, his own knee in the shot before, and after. (00:41:55)
Continuity mistake: After suffering a humiliating beatdown, Jason drives to Bruce Lee's tomb. During the scene the difference in lighting when the camera is closer to the car and when it's in other positions is like day and night, almost at least; the car is moderately lit by direct sunlight in the former, and the other shots were made later in the day when the last rays had gone, in a stark change. (00:41:20)
