Continuity mistake: Christie triggers Secord's odd tomato juice fetish, and they have sex. She wakes up and checks out the katana in the wardrobe. The sword floats shaking in different ways depending on the camera angle, and the lighting wildly differs as well. (00:29:00)
Continuity mistake: Christie battled the musclehead molesters and her love interest didn't lift a finger to help. He then abuses his cop powers driving her around without her consent; the boulevard he's driving through changes between shots. (00:25:15)
Continuity mistake: After the aerobics class, Christie tells her friendly cop stalker that coffee is bad for his health. In that particular shot she has a sweaty lock of hair sticking to her neck. In the rest of the scene her bouffant 80s hair is styled differently. (00:22:55)
Continuity mistake: When the cops surround the black ninja 'mortally' wounded and still find a way to get killed, the dangerous ninja is in full sunlight in the first angle, then he's in the shade. (00:10:45)
Continuity mistake: After failing to outrun the patrol car on the dirt road (without attempting to lose it in the tree or anything), the ninja turns around and jumps over it. The younger cop in the passenger seat raises his hand and sticks it out of the window; it's there in two shots, and not in the close-up. (00:06:45)
Continuity mistake: When the first victim of the ninja arrives at the designated spot for the ambush, he stops the golf cart and in a long shot he reaches for his club. In the closer angle the girl on the cart is in a pose inconsistent with what previously shown, and moments later he asks the bodyguards to help him search the ball, holding the club in a pose that changes at the cut. (00:03:30)
Continuity mistake: When Yamada causes Christine to faint and release the evil spirit, her body lies on the floor at an ever-changing angle throughout the scene (her feet are pointing 4 o'clock initially, but when the Black Ninja becomes the Zombie Black Ninja they are at 6, and they are at 8 when Yamada looks at the possessed monks). (01:19:25)
Continuity mistake: Christie enters the temple on the hill. When she approaches the altar, the red cloth is draped over it in differently from before. Similar mistakes (although nowhere nearly as blatant) happen between cuts when Ninja Christie and Yamada fight in front of the corpse. A HUGE instance of the mistake though happens when the evil spirit migrates from Christie's body to its previous host, though; the body was fully covered by the red shroud, and then not at all. (01:17:40 - 01:19:35)
Continuity mistake: The police arrives at the house under construction with three patrol cars. Watch as the cops get out of the cars and take position; their positions do change between shots - for instance, one cop stands behind the open passenger door of the car in front of him, and in the next shot he's still running towards it, and the guy behind the driver seat-side door of the other car points the gun with both hands first, then just one. (01:10:55)
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)
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)
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: 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)
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)
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)
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)
Continuity mistake: When Yamada stops the hearse, the shadow of the vehicle doubles in size between shots. (00:57:10)
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)
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)
