Continuity mistake: A spirit knocks Christine over and gives her a bloody lip. Her boyfriend tends to her lip, which is very swollen. As she sleeps, there is a close up of a fly going into her mouth between her lips that are not swollen at all. After she swallows the fly, she sits up and her bottom lip is swollen again.
Revealing mistake: When Christine is looking at the obituaries in the café, one of them is for Fredericka S. Freund. However, once you get past the first paragraph the obituary seems to be for Dr. Mary Allen Engle (nee English). Also, they forgot to put "Dr." before Freund's name. It may not be a coincidence that the Property Master for the movie is named Ellen Freund.
Question: Was miss Ganush alive when she first attacked Christine, or was that the first manifestation and torment of the Lamia? The attack and it's effects seem highly consistent with what happens to Christine later on, and the frail old lady is just too powerful and durable for someone who dies a day or two later.
Question: Christine needs $10,000 for a dangerous seance, so she goes to the shed to gather up some items to pawn, whereupon she again encounters Lamia (as Mrs. Ganush). Christine uses her ice skate to slash a rope that conveniently drops a 100-lb blacksmith's anvil on the demon's head. After the demon vanishes, the anvil, rope and chain are seen on the floor where they fell, so it wasn't just a fantasy sequence. Why does petite little Christine Brown (or anybody, for that matter) have a 100-lb blacksmith's anvil suspended 8 feet in the air with rope and chain out in the shed?Charles Austin Miller
