New this month Plot hole: When Mr. Loren introduces his wife to everyone, he tells her, "You know Watson Pritchard of course." That can't be because at the beginning of the movie the characters are asking if any of them know Frederick Loren. No one personally knows him including Watson Pritchard. He says, "I don't know him, all the details about renting the house were done by mail." If that's the case, it's impossible for Annabelle to know Pritchard since Frederick invited all the guests without his wife's approval. (00:34:05)DrLoomis1978
New this month Plot hole: Even if Dr. David Trent's and Annabelle Loren's elaborate plan had worked flawlessly (framing Nora Manning for Frederick Loren's death), the fact remains that they faked Annabelle's death for everyone to see, which would immediately arouse suspicions for investigators. Even if Annabelle and Dr. Trent somehow fled the scene before the police arrived the next morning, their actions would still raise many questions that implicated them; thus, their clumsy and convoluted scheme was far from being the "perfect crime" they imagined.Charles Austin Miller
Other mistake: Once Dr. Trent enters the bedroom where Mrs. Loren is lying down "dead", they begin talking. Trent says "At first I couldn't get Nora to protect herself with a gun." There is no scene in the movie where he tries to convince her to use the gun, Lance is responsible for that. (01:02:25)DrLoomis1978
Other mistake: When Lance leaves Nora to go have a meeting with the remaining people in the house and they accuse Loren of murder, his room is locked from the inside but when he returns he opens the door without any trouble.
Factual error: In reference to the skeleton in the pit, a skeleton with its flesh burned away would have nothing to hold it together. Frederick states it is Dr. Trent's skeleton. For him to run wire through the skeleton would have been impossible in the time he had. He had only a few minutes at best before his wife came down. He'd have had to fish the loose bones out of the pit, wire them all together, attach the whole thing to the puppeteer rig, and put it back in the pit.Jason Hoffman
