Continuity mistake: Mr. Stillwell limps his way into the parking lot after work, his jacket on his shoulder. He gets blindsided by an ugly dude who punches him away and...the jacket is gone, lost forever, not on the ground, just vanished. (01:08:00)
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)
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: 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: 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)
Other mistake: Throughout the dance club sequence, Kelly in several shots, from the very opening when she is in the background, up until everyone gets on the dancefloor, can be spotted with a guy standing next to her in a shirt similar to the protagonist's. But she has no date for and she came with a couple of girlfriends. (01:10:00)
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)
Revealing mistake: RJ does some breakdance routine before inviting everyone on the dancefloor. As he does the final kip-up, the white dude in blackface who bodydoubles him nearly loses his wig. (01:11:40)
Factual error: For the climax of the movie, the bad guy arrives from New York to Seattle, and hops on a limo with a California license plate. (01:14:20)
Revealing mistake: The TV commentators for the final fight sit at their table with bleachers in the background, but the other shots of the 'arena' show it's nothing more than a gym with everyone sitting at the same level. (01:16:20)
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: 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 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: 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: 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: In his fight with Sugarfoot Peter Cunningham, Van Damme unbalances him right away and starts kicking him while he staggers to the ropes. The clock shows 1:52 to the end of the round, but in the mere space of a kick (and a camera cut) it jumped to 1:48. (01:26:35)
Continuity mistake: The time jumps ahead from 1:23 to 1:14 when Van Damme throws his second opponent in the ropes wrestling-style. (01:27:20)
Continuity mistake: Scott and Ian get in the ring to carry Frank away. Dean is holding the second ring up with his right arm, which becomes the left at the cut. (01:27:30)
Audio problem: Ian gets in the ring to obviously canned crowd cheers preceded by a completely unnatural pause with the boos drowned out. (01:28:20)
