Continuity mistake: Dean flies off the ring when the ringside clock is at 1:07 and lands at 1:03. That's a pretty long fly, even if it was a spinning kick from Van Damme to knock you off your feet. The ref then calls the match off when the countdown is at 1:04. (01:25:35)
Continuity mistake: The Karate Fight Emcee motions the two teams to get quiet after their ring entrance. He does it holding the arena microphone in his left hand, which becomes his right hand all of a sudden, since the left is holding his cue card. (01:19:05)
Continuity mistake: Waiting for the match to begin, Kelly tells her cute friend "That was so much fun last night" as some dweeb stares at them. The chair next to Kelly is empty, and will be in other shots by the same angle, but in wider views there's a girl on that seat. (01:16:35)
Continuity mistake: When the "Seattle Sidekicks" get on the ring apron, Kelly is standing in the first shot, already seated in the next shot. (01:18:55)
Continuity mistake: In the locker room before the fight, Ian tells Frank and the others "Warm up well, guys." The other person is taping his wrist in the first shot, his palm in the next, and back to the wrist at the cut. (01:17:05)
Continuity mistake: When RJ slides into the dancefloor after the interpretative dance routine of the couple in red, he does it right away in the closer view, but in the wider angle he starts more from afar, and Jason is clapping instead of standing all stoic with his arms folded. (01:11:10)
Continuity mistake: In the establishing shot of the disco joint where a couple is breakdancing, notice in the audience a guy with a purple and teal gym jacket and pants. Later the protagonist and his sidekick park their car and as they walk towards the entrance, here's that same guy just now arriving as well. Same goes for other extras like the girl with fuchsia shirt and white pants. (01:09:50)
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)
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)
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)
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)
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)
