The Amityville Horror is a 1979 horror film based on a novel by Jay Ansen. It chronicles the (supposedly true) events that befell the Lutz family, who moved into 112 Ocean Avenue in Amityville, New York only to move out 28 days later, claiming to have been terrorized by paranormal phenomena there.They discover that the house was the scene of a multiple murder, when the previous owner, Ronald "Butch" DeFeo, Jr., had shot and killed six members of his family on November 13, 1974. During their stay in the house, the Lutzes start to experience various phenomena that tell them that whatever malevolent force drove DeFeo to such violence might still be there...It was followed by a series of sequels and a remake:
Artifacts of Doom: Following the third movie, the house is no longer actually featured as the main setting. Rather, its evil is passed on through certain objects that wind up in new homes, turning them in ersatz Amityvilles. These objects include a lamp, a clock, and a mirror.
A lot of the drama and even some of the horror in the movie centers around money problems: Kathy's brother loses $1500 in cash, George bounces a check and his business seems to be in trouble. Finally there's the very real concern that the house, aside from being evil, is an $80,000 investment that's going From Bad to Worse.
The children are being terrorized by the house as much as the adults, and there's a growing possibility that George will hurt them himself.
Then there's that most fearsome and adult of adult fears: in one scene, George can't get it up.
The Alleged Car - Father DeLaney's car flies to pieces when he's on the way to visit the cursed house, almost killing him and Father Bolen.
Arbitrary Skepticism - For men who have devoted their lives to God, the priests in this movie have an awfully hard time accepting the existence of Satan.
Ax-Crazy - George is implied to become this over the course of the movie and he develops an overwhelming fondness for chopping firewood.
Bloody Horror: A specific part of the wall in the Amityville House's basement starts dripping blood at night, and forming, a stream leading George to it. It's revealed later on that the basement used to have a morgue, and that people were also tortured there.
Cat Scare: George Lutz, lost in thought, is playing with one his cigarettes when suddenly a cat pops up in his window and scares the hell out of him.
Present Day Past: While supposedly taking place in 1974, the (1982) movie shows a Rocky posternote Rocky was released in 1976, a Walkmannote prototype built in 1978, available in the US in 1980 and cars from the 80s.
Roman à Clef: While based on the DeFeo family, all names were changed.
Everybody Lives: The cursed clock brought from the original house causes a Reset Button Ending to avoid getting destroyed in an explosion, only to be smashed by Final Girl Andrea, who retained her memories of everything the clock caused, before it can do it again. It's also implied that Rusty and Iris actually remember everything as well, except for Jacob and Lisa, which could be attributed to their possession.
"Groundhog Day" Loop: It's implied this was the case before Andrea remembered everything at the end. When the film begins, Andrea has one of Jacob's measuring tools, which she claimed she had "For protection." She later tried to use the same tool to destroy the clock, and when it reset everything, she still had it. Only the potential loop is finally stopped because Andrea managed to destroy the clock this time.
Heroic Sacrifice: Andrea tries to cause an explosion thanks to a leaking gas pipe, which would kill her and destroy the clock. But the clock ends up rewinding time back to when the movie began, so Andrea survives.
Indian Burial Ground: According to the the crazy psychic lady, the Indians dumped their crazy people on this land to die and that the bodies are still there, effectively making it an Indian Burial Ground, even though they didn't bury the bodies.
Also a bit of a subversion in that the white guys aren't getting punished for being 'disprespectful' so much as for being dumb enough to build a house right atop Angry Demon Central.
Room Full of Crazy: The hidden room under the house is different between films, but unpleasant and crazy anyhow.
