Continuity mistake: When Stephanie talks to Ben by the fence about him taking her to the ball, her hair changes position over her right shoulder between shots. (00:41:20)

Sammo ★

Other mistake: The 4 kids just snuck into a party. Some jocks begin making fun of Ben, calling him "the chinese Jordan." Daric walking off to check on their puking friend bumps into one of them on purpose. During this sequence, notice that one of the guys is holding a paper cup completely empty just for show, and in the reverse shot it even flips suddenly. (00:37:25)

Sammo ★

Continuity mistake: When 'Gabe', the employee of the convenience store holds the patently false ID that Ahn gave him, his index finger is at the very top of the card, on the corner, and it is in a different position in the reverse shot. (00:35:40)

Sammo ★

Continuity mistake: Ben finally is asked to get on the court to play. The girl with braids cheers him wildly in a close-up, and the girl behind her is holding her yellow sign with her left hand. Cut, and she is using the right hand. (00:21:55)

Sammo ★

Character mistake: When Ben and Stephanie are studying, she repeats the stages of mitosis (which should be prophase, metaphase, anaphase, telophase, with minor differences in the way textbooks divide them) out order; anaphase, metaphase, interphase, prophase. She is supposed to be an A student and Ben, who is also smart and reading from the notes and textbook, says she is right. (00:18:55)

Sammo ★

Continuity mistake: Ben is happy because he made the team. He sees Stephanie on the sidewalk, reading. He approaches her; she says "Oh hey, Ben!" closing the book twice and in different ways. (00:13:55)

Sammo ★

Continuity mistake: When Christie kicks a cop head-first into a gravestone shattering it (the gravestone, not the head, although one wonders how just the latter could happen), the stone breaks in two completely different ways in separate shots. (01:06:55)

Sammo ★

Continuity mistake: When the ninja parries the baton strike from the guy making all the swooshing noise, her right side of the body (and her arm, specifically) are already prepared to hit the second guy while the left hand brings down the baton. The next shot though opens with her right arm low and her left arm high over her head. (01:06:45)

Sammo ★

Continuity mistake: When the patrol car chases the ninja at the funeral shooting at her with a shotgun, there's a POV shot from the driver, who has his right hand at 12 o'clock on the wheel. Reverse angle and the hand is gone. It happens again moments later when the driver stops the car, and at the cut it switches from 10 to 2 o'clock with opposite hands. (01:05:50)

Sammo ★

Revealing mistake: In the sequence with the ninja knocking two policemen off their bikes at the funeral, the one on the right goes down (not to dodge, but acting like he's being hit) a second before her foot actually hits. (01:05:40)

Sammo ★

Revealing mistake: At the funeral, Ninja Christie shoots two arrows. She prepares to shoot a third, but meanwhile (in the shot where a widow is looking around worried and a man in a light suit pulls her away) another guy just dies for no reason hit by something invisible. (01:05:10)

Sammo ★

Continuity mistake: At the funeral, Ninja Christie shoots one arrow, then a second. The officer dies holding one hand to his chest in the shot, both in the next. (01:05:05)

Sammo ★

Continuity mistake: When Yamada stops the hearse, the shadow of the vehicle doubles in size between shots. (00:57:10)

Sammo ★

Continuity mistake: When Yamada knocks out the group of three guards he failed to sneak past at the morgue, the guard to the left goes down dropping the nightstick at distance and at a certain angle. Yamada walks past them and the baton is closer and at a different angle. (00:55:55)

Sammo ★

Revealing mistake: The first time we see the legendary Sho Kosugi properly in action, he knocks out a guard, then he throws a shuriken at another and fights him. He dodges his baton, kicks him, and then you can see clear as day the awkward moment when the stuntman just stops and waits for the follow-up push-kick towards the dumpster. (00:55:20)

Sammo ★

Continuity mistake: When the priest tries to read from a scroll and gets laughed off by the ninja demon, he is holding the scroll in a different way between shots - just use the little string as reference. (00:51:10)

Sammo ★

Continuity mistake: When Billy pays the wise man from the Orient, the wad of bills does a 180° between shots. (00:47:45)

Sammo ★

Other mistake: This is just baffling; in the scene where Christie is wearing a rather sweat-stained pink top and Billy turns the music off asking her "Where have you been?" they are the only ones in the room, but someone out of frame throws what appears to be a puppet on Christie bed (!?). (00:45:45)

Sammo ★

Audio problem: When Christie moves on to the second girl in the hot tub to strangle her, she screams "N-noooo!" but her lips and facial muscles don't move. (00:44:20)

Sammo ★

Continuity mistake: Christie is making out with the sleazy cop. We get a close-up of the poisoned ring and how she turned it, and she is ready to strike. She has both arms over his shoulders, both for the close-up of the fatal gesture, the arm is out of the way. (00:44:00)
