Revealing mistake: When the Lawyer plays the videoclip on the laptop, the stop button is pressed down all the time, instead of the play button. (00:14:40)
Revealing mistake: When Arthur hits Cyrus at the end, Cyrus flies back and hits the floor. The floor is meant to be solid and sturdy, yet clealy wobbles when Cyrus hits. (01:18:35)
Continuity mistake: When Shannon Elizabeth is attacked by the ghost she has scratches on her face, then when they are all sitting huddled in the corner the next shot of her, there are no scratches on her face. (01:30:01)
Rafkin: There are ghosts in the basement.
Maggie: This basement?
Rafkin: Of course this basement! What is it with you people? If it was the basement next door I wouldn't give a shit, would I?
Trivia: While the Withered Lover is stated to be proactive for the side of good, two other ghosts are never seen actually attacking or scaring someone. The First Born Son is more of a taunter and prankster, though the Torso seems to be more or less harmless as he doesn't even hurt Cyrus. The Dire Mother is also seen as harmless by herself, but she is accompanied by her disabled son Harold who carries an axe for protection.
Question: At the end, is Cyrus a ghost or a real person? If he's a ghost, why can he be seen without the glasses?
Answer: He's alive. He faked his death at the beginning of the movie to get Arthur and his children into the house, because only then would he be able to force Arthur to engage the 13th Ghost. When Cyrus is seen at the end of the movie, he is disguised with the blood patch to make it appear that he is dead to a casual observer with the glasses (everyone is wearing them at this point) and prevent Arthur from being able to figure out his plan.
Suggested correction: Cyrus was an occultist, it is presumed that this video was haunted. That can also explain why he answers what they key is for in the video after someone asks what it's for.
This theory does not hold up because Cyrus is alive. He's just been wearing a prosthetic neck piece with a popped blood pack in it to appear as a ghost the whole time, in case he's seen walking the house during the plan.
