The Changeling

The house seen in the movie in real life doesn't and never actually did exist. The film-makers could not find a suitable mansion to use for the film so at a cost of around $200,000, the production had a Victorian gothic mansion facade attached to the front of a much more modern dwelling in a Vancouver street. This construction was used for the filming of all the exteriors of the movie's Carmichael Mansion. The interiors of the haunted house were an elaborate group of interconnecting sets built inside a film studio in Vancouver.

After Claire comes running down the stairs screaming she yells to John but mistakenly calls him George for George C. Scott. This has been removed from some versions.

The Japanese theatrical version contains the alternative ending theme, titled "Pike", sung by Makigami Koichi, a pseudo-kabuki vocalist who led the rock band called "HIKASHU", replacing the original "Music Box" theme song conducted by Howard Blake. The local Japanese TV (dubbed) version also contains the similar "Pike" theme from "HIKASHU", but while the original theatrical version was in Japanese as supposed to be, the song in the TV version was remarkably sung in English.
