Overview
Amityville 3-D (also known as Amityville III: The Demon) is a 1983 supernatural horror film directed by Richard Fleischer and starring Tony Roberts, Tess Harper, Robert Joy, Candy Clark, Lori Loughlin and Meg Ryan. It is the third film based in the Amityville Horror series, it was written by William Wales, a pseudonym for David Ambrose. It was one of a spate of 3-D films released in the early 1980s, and was the only Orion Pictures film filmed in the format.
Due to a lawsuit between the Lutz family and Dino De Laurentiis over the storyline (which did not involve the Lutz family), Amityville 3-D was not initially promoted as a sequel, and the name Lutz is never used in the film. However, the film does make a reference to the original Amityville Horror story. The character of John Baxter (Roberts) is loosely based on Stephen Kaplan, who was trying to prove the Lutzes' story was a hoax at the time. It was panned upon release.
Plot
After he exposes a pair of con artists with his partner Melanie in the infamous 112 Ocean Avenue house in Amityville, journalist John Baxter is persuaded to purchase the house by real estate agent Clifford Sanders. While preparing the house for John, Clifford investigates footsteps in the attic. He is locked in the room, where a swarm of flies attack and kill him. John believes Clifford died of a stroke, even after Melanie shows him some photos she took of the real estate agent before his death, depicting him as a rotting corpse.
While John is at work, he nearly dies in a malfunctioning elevator. Simultaneously, Melanie experiences bizarre occurrences in John's house. She is found later that night by John, cowering and hysterical against the wall. Her attempts to convince John that something is inside the house fall on deaf ears. Later, while looking over blowups of the photos of Clifford, Melanie discovers a demonic-looking face in the pictures. When she attempts to show the photos to John, she is killed in a horrific car accident. Melanie's death is ruled accidental by everyone, including John, who remains oblivious to the evil in his home.
