Frederick Loren (Vincent Price), an eccentric millionaire, is throwing his "party" for his fourth wife, Annabelle, with the stipulation that the power will be out and all doors will be locked at midnight, allowing no accessible escape. Anyone who survives the night will be awarded $10,000. As the night progresses, however, it becomes clear that this is no game by the host — the partygoers are indeed trapped here with malevolent ghosts, murderers, and other terrors.
Matching up with William Castle's Signature Style, the film originally released exhibiting one of his past-the-fourth-wall gimmicks — in this case, a model skeleton would be elevated over the movie audience during the climactic scene, and would then be reeled back during the shot of Loren winding its thread back into the reel (which is why this shot seems to go on a bit too long without the gimmick).
The film was remade forty years later by Dark Castle Entertainment. It's also in the Public Domain, and can be viewed and/or downloaded legally for free online. The film was "officially" released to DVD in 1999 from Warner Home Video, and Blu-ray in 2014 from Shout! Factory as a part of their second Vincent Price collection.
This film contains examples of:
- The Alcoholic: Pritchard, after his brother and sister-in-law were murdered in the house. He spends most of the movie drinking and doomsaying.
- Ambiguous Ending: Was everything that Annabelle and Dr. Trent caused really just one giant scheme built on superstition with no true supernatural elements involved, or is the house truly haunted?
- Asshole Victim: Annabelle and Dr. Trent really had it coming.
- As You Know: Just before the end of the movie, Annabelle and Dr. Trent stand around discussing the details of a plan that they not only both know, but which is already 90% complete.
- Batman Gambit: Terrorize Nora into a state of hysteria thinking Loren is trying to kill her, causing her to kill him in "self-defense".
- Bizarrchitecture: All the exterior shots of the titular mansion are of Ennis House, a Frank Lloyd Wright-designed structure built in emulation of Mayan temples, but it looks like a typical Victorian-manor soundstage from the inside.note
- The Bluebeard: Loren is on his fourth wife. The first one disappeared, and the second two died of heart attacks, despite being in their 20s. The fourth one is scared to death during the course of the party. She was a Gold Digger planning to murder Loren for his money, however, casting an unsavory light on the intentions of the first three. In retrospect, however, we can't be sure that his first three wives did die under such mysterious circumstances, since the person who described them was trying to create an alibi for Loren's eventual demise.
- Body in a Breadbox: A severed head turns up in an unsuspecting character's suitcase. It's a fake.
- Book-Ends: The first and last lines are spoken by Pritchard to the audience.
- Break the Cutie: Traumatizing Nora is a crucial element in Annabelle's scheme.
- Character as Himself: The skeleton is credited as "by itself".
- Colliding Criminal Conspiracies: Loren and Annabelle are both plotting to kill each other by using the party to their advantage.
- Closed Circle: Once the clock strikes midnight, the guests will not be allowed to leave.
- Creepy Housekeeper: One appears to scare the living daylights out of Nora.
- Dem Bones: The living skeleton that appears before Annabelle. It's actually Dr. Trent's skeleton, which is controlled by Frederick.
- Domestic Abuse: Loren skates along the edge of this as he prepares his reluctant wife for her party.Loren: Are you ready, dear?
Loren: [grabs her hair and pulls it] Are you ready, dear?
Annabelle: Yes, damn you!
- Annabelle, meanwhile, has tried to poison him at least once before the events of the film start.
- Empathic Environment: That House is easily believable as haunted.
- Enclosed Space: "You won't have a chance to change your minds later... because there won't be a way to get out."
- Falling Chandelier of Doom: Nora is is almost killed by a falling chandelier within minutes of entering the house.
- Fan Disservice: The poster shows a woman in a slinky dress, which is sliding off her shoulders. She is being hanged.
- The Fourth Wall Will Not Protect You: Used in the ending: "They're coming for me now... and then they'll come for you."
- Gaslighting: What Annabelle and Dr. Trent were doing to Nora in the hopes that she'd wind up shooting Mr. Loren for them.
- Ghostly Glide: The ghostly figure in the cellar later revealed to be one of the caretakers that terrified Nora moves by gliding rather than walking.
- Ghostly Goals: It seems that Frederick has come back from the dead to haunt his wife. Subverted as it is part of his scheme to get rid of her.But you're not going to live to enjoy it!
- Hand Gagging: Jonas grabs Nora from behind, clamping a hand over her mouth and warning her that she doesn't belong here and should come with him.
- Haunted House: Well, it's on a haunted hill. What do you expect? Though in the end it's left up to debate if the house truly is haunted, or if it was just an elaborate hoax.
- Haunted House Historian: Pritchard, who just can't stop talking about all the hideous murders that have happened, and how the ghosts are going to kill everyone before morning.
- Hollywood Acid: Doesn't eat at bone or the winery container it's stored in. Or for that matter, strings.
- Hysterical Woman: Nora. Invoked. Annabelle and Dr. Trent are trying to terrify her to the point of killing Loren in 'self-defense'.
- Implied Love Interest: Lance and Nora. He saves her several times, keeps her secret, and when he goes to look for a way out he says he'll come back for her if he finds one. She's very concerned when he gets locked in the basement, and even after she accuses him of not believing her she begs him to get her out. They also happen to have adjoining rooms.
- Informed Attribute: We're informed at the beginning of the film that Ruth is a gambler. Are we shown anything of the sort? Nope.
- It Was Here, I Swear!: Happens to Nora a lot. When Lance finally sees one of the severed heads that she insisted was there, he just grabs it by the hair and brings it with him to show everyone.
- It Works Better with Bullets: Nora is baffled that Frederick is still alive after she shot him. He calmly explains that he had loaded her gun with blanks.
- Kansas City Shuffle: The film is essentially a whole load of characters going around trying to trap and falling into the traps of others.
- Large Ham: Frederick Loren. He's played by Vincent Price, so would you expect anything less?
- Maybe Magic, Maybe Mundane:
- After all is said and done, the existence of actual ghosts is left ambiguous.
- There is that spot of blood that keeps shows up on Ruth's hand, even after she has washed it off...
- Noble Demon: If Loren is to be taken at his word, he's going to face the courts willingly after killing Annabelle. Granted, he's leaving out that he intentionally killed her, but it would have been much easier for him to make Nora look crazy and simply let everyone think Annabelle vanished.
- No Fourth Wall: The film opens with both Pritchard and Loren speaking directly to the audience. This would have been even more blurry in the original theatrical run, where William Castle would dangle plastic skeletons from the ceiling during scare moments.
- The Fourth Wall Will Not Protect You: Pritchard's speeches in particular are more of a warning, as if the audience is in danger of catching the ghosts' wrath themselves.
- Old, Dark House: Well, it's more like a castle, but it's certainly old and dark, especially once the electricity is cut.
- Ominous Pipe Organ: One of many things used to scare the guests.
- On One Condition: "I think you all remember the bargain we made about staying all night: $10,000 a piece."
- Out, Damned Spot!: The House has a bloodstain that cannot be cleaned up, no matter what. It gets even creepier when it starts dripping on Ruth's hand.
- Out-Gambitted: "Little did you know, as you were playing your game of murder... that I was playing too."
- The Place: The House on Haunted Hill.
- Prophet Eyes: Mrs. Slydes.
- Rain of Blood: Drops of blood fall from the ceiling onto the hand of one of the guests. Watson Pritchard tells the woman that the house has marked her. Notable in being one of the scenes that supports the idea the house is actually haunted.
- Screaming Woman: Nora Manning. Justified in that Annabelle's plan is entirely reliant on keeping Nora on edge the whole time.
- World of Ham: Oh Dear God, yes. And it's glorious.
