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)
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: 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)
