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)
Continuity mistake: Dean finishes his absolute beatdown of the protagonist putting a knee on his back and choking him against a bench. He's holding the bench gripping the tip of the feet first. Deeper down in the next. (00:40:05)
Continuity mistake: Jason gets kicked over the buffet table. A girl in a dress watches the scene with one hand under her chin, both hands together, hands separate. (00:39:40)
Continuity mistake: When Scott throws the drink on the back of Jason's shirt, Kurt McKinney is casting a huge shadow right on the face of Dale Jacoby, unlike what happens when they talk. (00:39:05)
Continuity mistake: Ian Reilly approaches the three guys who called him over his own dojo. The goons on both sides have a different position between the two shots - for instance, the one to the boss'right does not and then does indeed have his hand on the ring. (00:37:00)
Continuity mistake: When Scott pervs Kelly and Jason making out, his right hand is down. In the closer angle when he holds back Dean though, his hand started already up, rubbing his belly. (00:36:35)
Continuity mistake: Kelly removes the ribbon from the package in close-up; it falls towards the camera, but in the previous shot her hand was sweeping the corner of the box away from that direction. (00:35:50)
Continuity mistake: Scott white-knights the poor RJ that is being cradled into oblivion by the bulky bully. He jumps over the railing and kicks Scott; obvious is the lack of continuity; the guy with the striped white and green shirt that had folded arms and now is just standing there with his arms low is very obvious, but Scott himself was holding RJ by the thigh and in the second shot, to facilitate the kick, he is holding it by the far end of the leg. (00:22:05)
Continuity mistake: RJ tried to kick Scott away but only pushed himself off the table. Scott picks him up; the light of the two shots is blatantly different. (00:21:50)
Continuity mistake: When Scott backs RJ against the railing in front of the burger joint, some fellow bullies in the background change position between shots (the dude with the little ponytail had his left arm raised in guard and it's down, the guy with the horizontal stripes is suddenly with folded arms). (00:21:40)
Continuity mistake: Scott begins scarfing the burgers; instantly he gets a bunch of mayo and ketchup on his thumb, but it's gone at the cut. (00:20:10)
Continuity mistake: When Scott gets RJ with the pressure washer, he wets the left side of his shirt - but in the hijinks by the road constructions, RJ sports a T-shirt wet on his right side. (00:16:45)
Continuity mistake: RJ is skating away from an angry Scott he just bit. In the sequence with two construction workers and a ladder, the natural light changes completely between shots (no direct sunlight at the beginning, clear shadows and sunny area in the close-up of the board tricks). (00:16:55)
Continuity mistake: Scott hoses RJ with the window cleaning machine; in the first shot RJ is really close to the fence, but the skateboard slips on sidewalk that is somehow already wet. Then Scott sits on him and begins brutalizing him, with the cement around RJ's head that is wet or dry depending on the shot, and when he gets up it's like they never fought with any water involved, the sidewalk is all dry. (00:16:35)
Continuity mistake: The obese comic relief is mocking his dad's speech as he puts him to work washing windows. At the first cut when he approaches the window you can tell time (and takes) passed, because the wet area on the wall under the window changed size considerably. The wall even basically all dries up the moment Scott spots RJ. (00:16:05)
Continuity mistake: The protagonist is all hyped-up because of his planned cemeterial trip. He begins training in his garage; when he kicks both the punching bag and the speedball, or at least attempts to, the mats on the floor change position between shots. (00:15:00)
Continuity mistake: When RJ falls off the shelves that Jason hastily put back in place earlier, the kid is climbing on different set of shelves; he approaches those closest to the window, but falls from some that are in the middle of the case. (00:13:00)
Continuity mistake: RJ in the garage is doing his thing 'rapping' and doing whatever passed for music in the 80s. Part of the scene must have been left on the editing room floor, because after the close-up on his legs doing the moonwalking-y act he is about 1 meters away from the previous spot, under a different light, mounts on a box that had books on that corner (they are pushed back now), and even falls down on a bamboo mat that was not there before. (00:12:50)
Continuity mistake: RJ offers to show Jason what he can do instead of wooden dummy sparring. Jason looks at him busting moves as he leans against the dummy with both arms, but in the first shot he had only the right arm in position. (00:12:30)
