Continuity mistake: When the Black Ninja has been unmasked, somehow both warriors get scared by the cop sirens. Christie escapes through a window; in the first shot the window is half-opened, in the second, all of a sudden all she has to do is push the fly screen, as the window frame has been removed. (01:10:35)

Continuity mistake: When the Black Ninja drops a large wooden board on Yamada, Sho Kosugi's hands are positioned differently between shots, and when he breaks it, the two large pieces end up in different spots depending on the camera angle, even few seconds when the Black Ninja keeps going Donkey Kong on their opponent throwing more garbage at him. (01:09:35)

Visible crew/equipment: Inside the house under construction, the Black Ninja drops a bunch of dirt from the top of the stairs (an action she will repeat later). The rubbish hits the camera that shifts slightly towards the end of the shot. (01:08:50)

Sammo ★

Continuity mistake: When Sho Kosugi breaks some boards that block the entrance to the house, the leftmost board is just chipped in close-up and fully broken in the following shot. (01:08:25)

Sammo ★

Continuity mistake: In the opening phases of the fight between the two ninjas, the one possessing Christie tries to stab Yamada through a window. In close-up, Sho Kosugi has both hands on the brick sill, but in the next shot his left hand is still distant and closer to the doorframe. (01:08:20)

Continuity mistake: Virgil wins a portable CD player thanks to the candy bar contest; the first view of the results, featuring his picture, simply shows his name and score followed by Ben and other two people. A close-up of the same printed sheet inserts also the word "Runners up." (00:45:35)

Sammo ★

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)
