Trivia: George Lucas originally wanted to set portions of the film in a haunted mansion where Indy would encounter various ghosts and specters, but director Steven Spielberg protested, as he had made "Poltergeist" a few years earlier and didn't want to repeat the same scares and imagery over again in an Indiana Jones film. Other early ideas had Indy searching for the fountain of youth and encountering the Chinese mythological figure the Monkey King.

Revealing mistake: When Walter Donovan is dying after drinking from the wrong cup, watch the over-the-shoulder shot where we see his hair grow long suddenly - for some reason, this shot was filmed in reverse, as the fire coming from the candles/torches behind Elsa is not burning upwards, but appears to be "sucking" back downwards.
