Poltergeist

Heather O'Rourke kept the pet goldfish Carol Anne has in the film.

Many viewers have pointed out that only one of the houses in the neighborhood is affected by ghosts even though the whole neighborhood and many other houses were built on the same ground. However, there are two sections of the movie that explain this discrepancy: one in which Steven tells a prospective buyer that his family was one of the first to move into their neighborhood, and another in which Steven's boss mentions that Carol Anne was born in the house. The novelization makes the connection more explicit: because Carol Anne was born in the burial ground, the spirits gravitated toward the Freeling household, attracted by her life force.

After the credits and the logo of the MGM lion is shown, we hear children laughing. Fans of the film have assumed that the laughing children are those who have been released from the beast and have crossed over the threshold into the next life.

For ABC's 1985 network television premiere, Marty's hallucination is altered so instead of him ripping his own face off, he sees his face rapidly deteriorate briefly.
