Continuity mistake: When Yamada leaves the temple, the shadows on the matte painting long shot don't match at all the shadows on the closer angle of the stairs. (01:22:30)

Sammo ★

Continuity mistake: When Christine looks at Yamada before falling unconscious, the sword scabbard is right next to her at the bottom of the frame, but it's at greater distance in the previous shot and rest of the movie (like when her boyfriend wakes her up), except when the black ninja rises, when it's gone. (01:19:15)

Sammo ★

Continuity mistake: When Christie draws her sword and brings it down over her stalkerish boyfriend (but alas, doesn't kill him), he clings to the bedframe with both hands, but has just one arm raised in the second shot. You'd think the arm is down on the ground for good as shown in the room view too, but in the very last shot he's again gripping the frame. (01:15:25)

Sammo ★

Continuity mistake: When the good ninja KOs the cops in the car, the hat on top of the last one is tipped in an entirely different way in close-up and wider angle. (01:13:10)

Sammo ★

Continuity mistake: During the close-up of Sho Kosugi looking languidly at Christie's boyfriend when the cops are taking him away, look at the blonde moustached cop behind him. His face is in the shade, and then suddenly in direct sunlight at the cut. Same for his fist as he holds the gun in this second shot; direct sunlight on it, shadow during the next close-up on the ninja. (01:11:25)

Sammo ★

Continuity mistake: After one of his coworker smashed a gravestone with his baton, a second cop gets close enough to the ninja to grab his/her arm. The ninja punches him away with a blow from right to left, which is not in continuity with the previous shot. (01:06:35)

Sammo ★

Continuity mistake: When Christie's wardrobe tries to suck her in, the items that are being drawn in and therefore slide on he floor, change between shots with no logic. For instance, we see an empty metal vase, then the same vase with marbles, then just the marbles. (01:02:00)

Sammo ★

Continuity mistake: The priest is praying and unknowingly almost exorcises the evil ninja, he is holding his onusa (the stick thingy) with one hand or both hands, and when they both speak Japanese the grip of the left hand differs between angles. (00:50:00)

Sammo ★

Continuity mistake: Once Christie is all tied up, the ceremony begins. Miyashima is holding a pipe that faces opposite ways between shots when he holds it with both hands. Still holding it with both hands he brings it to her lips, then in close-up suddenly he holds it with just one hand. (00:49:20)

Sammo ★

Continuity mistake: In the opening kick of the billiard fight, Christie's foot touches the Miller time lamp suspended over the pool table, which logically begins to undulate. In the next shot, the lamp is perfectly still and untouched. Similar mistake a minute later at the end of the scene; when she leaves using the window, the lamp is moving but almost comes to a complete halt, only to be back swinging wildly at the cut. (00:38:00 - 00:39:00)

Sammo ★

Continuity mistake: The scene where Christie eventually succumbs to the arcade machine begins with her top bearing a huge sweatstain throughout the whole length, but ends with the stain considerably reduced (to be fair, there is no frame of reference to categorically exclude that laser beams emitted from bootleg cabinets possessed by evil ninja demons double as dryers, but we can assume it's not the case). (00:33:15 - 00:35:20)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)
