Poltergeist movie was released in
1982, with two sequels to follow (Poltergeist 2 1986 and
Poltergeist 3 in 1988). The original, considered
to be one of the best horror flicks of the 80's, was
about a suburban family living in a haunted house.
Why was it haunted? Evidently the house had been
built on old Native American burial grounds, and those below were none
too happy about it.
