Continuity mistake: The first time Helen is at Cabrini Green and she goes through the medicine cabinet into the other apartment she has to actually crawl through the small opening in the wall where the medicine cabinet is, but when she goes back at the end to find the baby the hole in the wall has grown considerably, she just crouches and walks right through.
Continuity mistake: When Virginia Madsen goes to the bathroom in her apartment and opens the medicine cabinet. At this point Candyman's arm comes through the medicine cabinet but it only breaks through the upper part of the cabinet, leaving the lower part intact. The angle then changes to a side view to show his arm reaching straight out at her. The arm does not move downwards but in the next shot, as she turns to escape, the whole cabinet is broken through.
Visible crew/equipment: When Virginia Madsen and her friend are in her apartment, and are about to check out the mirror, they walk down a long hallway. At the beginning of this shot, they both pass the camera and it begins to follow them, displaying a shadow on their shirts as well as the wall. (00:13:40)
Continuity mistake: When Candyman gets Virginia Madsen in her kitchen he stabs her in the back of the neck and you see a good amount of blood, in one line, run down the middle of her chest but in the next shot not only has the blood changed place but there's now two lines of blood trickling down instead of just one.
Continuity mistake: When Candyman kills Dr. Burke, blood splatters on Helen, leaving three smudges on her right cheek, right along the jaw. These smudges keep moving around. First, she has a spot right next to her chin. After Candyman has cut her restraints, we get a close-up of Helen, and the blood by her chin is gone. As she gets up and prepares to climb out the window, another spot has appeared on her right cheekbone. (01:08:20)
Continuity mistake: When Helen is strapped to the gurney and sees Candyman floating over her, she starts twitching and screaming, making the nurses rush in and sedate her. But when the surveillance tapes from the same scene is shown, it plays out differently. The first time, Helen just shouts, "Murderer! Help!" and the nurses immediately arrive, on the tapes she screams for a longer time, and twice calls out, "He's here! He's under the bed!" (01:01:45 - 01:05:55)
