Continuity mistake: When Christie's friend checks out the katana, she is suddenly leaning with her right arm against the railing at the cut. (00:20:20)
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: 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: The male protagonist acts sassy about the Christine not liking cops and pulls over. His hand in the next shot is on top of the steering wheel, and in the first one it wasn't. (00:25:41)
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: When Billy inspects Christie's sword, he's holding it hilt up in the wide shot. In the close-up, he's holding it hilt down. (00:30:30)
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)
Continuity mistake: Christie takes a breather after she called Billy. The position of her hand on the receiver - her pinky and ring fingers are at a very peculiar angle that she can't easily change - are suddenly different at the cut. (00:33:40)
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)
Continuity mistake: When Ninja Christie fights a cop who was playing billiards, he fights her back with a pool cue. She jumps on the billiards table and chops his pool cue to pieces till he drops it. In the next shot, he is again holding the pool cue. (00:38:15)
Continuity mistake: In a moment during the fight scene between Ninja Christie and the cop playing billiards, she kicks him into a wall. His hand is raised in one shot but not in the next. (00:38:20)
Continuity mistake: In the fight scene between Ninja Christie and the cop playing billiards, she stops him from getting his gun then she kicks him into the wall. In the next shot, she somehow is again at the opposite end of the billiards table. (00:38:30)
Continuity mistake: When the policeman throws the billiard balls at Ninja Christie, the balls have a different position on the table depending on the camera angle and the pool cue appears and disappears from the table. (00:38:30)
Continuity mistake: Ninja Christie kills the cop playing billiards by slashing his face then throwing him onto a wall. The next shot shows that he instead flies out of the window. (00:38:50)
Continuity mistake: In the scene at the spa, notice how Christie lets nonchalantly go the towels she used as an excuse to get in the room with the ladies and the sleazy cop Jimenez. She does the deed killing everyone, then as she walks away look at the towels and their much neater placement on the bench. (00:43:05 - 00:44:35)
Continuity mistake: At the spa, Christie opens her robe. The darker haired lady-friend of the sleazy cop turns towards her noticing what she'd doing, but the following reaction shot begins with her still engaged in conversation; she notices the competition only a moment later. (00:43:10)
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)
Continuity mistake: When the possessed Christie seduces then kills the cop in the hot tub, he pulls away from her embrace after he realises that she's poisoned him; he's holding onto her with both hands. In the next shot, he's holding her with just one hand. (00:44:10)
Continuity mistake: When Billy pays the wise man from the Orient, the wad of bills does a 180° between shots. (00:47:45)
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)
