Continuity mistake: During the Sound Stage scene, Chucky and Tiffany kill the puppeteer by chopping his head off with wire. When the blood splatters all over Tiffany's and Chucky's faces, Tiffany's right eye is covered in blood. In the next shot there is no sign of blood in the eye at all.
Continuity mistake: Towards the end when Glen cut his father's arm off, you see him lying there screaming and bleeding. The blood from his arm on the floor is making a puddle and then it cuts to Glen's face. When it shows Chucky's arm (or stump) again, there is no puddle, just blood following the crack in the floor tile.
Continuity mistake: When Jennifer is getting ready for her date, the perfume is on the table in the first shot, but in the next shot, she is spraying it on herself.
Continuity mistake: Joan falls from the banister face up, but when the police see her, she's face down.
Suggested correction: She very obviously falls and lands face down.
Continuity mistake: When Joan walks in to see Tilly and Stan tied up on the bed, both Tilly's and Stan's feet are tied to the bedrail but are lying flat on the mattress. When Joan is set on fire, there is a shot where you can see Tilly's and Stan's feet again, only this time, they are elevated and resting on the bedrail they are tied to.
Continuity mistake: After Glen kills Chucky and begins crying, the blood spatter on his face changes slightly between cuts.
Continuity mistake: Before Tiffany kills Redman, he has a plate loaded with food. We then see him take a few bites in close-up as the camera circles around him, and then it cuts to his plate, and it's now essentially empty. The bites he's taking are not big enough to totally empty his plate in the time seen.
Continuity mistake: When Redman hears Tiffany running behind him and turns around, he places his fork down on his plate twice between cuts.
Continuity mistake: When Jennifer asks Joan to bring her a bottle of champagne, Jennifer's eyes go from wide open to partially closed between cuts.
Continuity mistake: When Joan is writing fake fan-letters to Jennifer, the letter she is writing changes between cuts (notice where it says "Sincerely, " which is completely different between the two close-ups). She also goes from not writing to writing between cuts.
Continuity mistake: When Chucky, Tiffany, and Glen are talking in the back of Jennifer's limo, when Tiffany tells Glen not to "worry about it" because "I've got that figured out too!", her right hand goes from up by her face to down by her side between cuts.
Continuity mistake: When Jennifer is auditioning for Redman, when Redman says he's going to go with his first choice, Jennifer's hand goes from up under her chin to down by her side between cuts.
Continuity mistake: When Tony Gardner is checking the Tiffany doll (right before it grabs his crotch), he puts both knees on the ground right before the shot ends. In the next shot, only one of his knees is on the ground.
Continuity mistake: When Glen has his first voiceover at the ventriloquist show, when he says, "I'm not like that at all," there's a small hair stuck to his face near his left eye. It disappears in the very next shot where you see him.
Continuity mistake: When Psychs the ventriloquist goes on stage, in the first shot, he doesn't have a cigarette in his mouth. In the next shot, one appears in his mouth. He has his arm extended in both shots, so while he is briefly off camera for about one second, he wouldn't have time to put the cigarette in his mouth, then re-extend it between takes.
