Trivia

The River Ghost's role was reduced in the final film, compared to earlier drafts: it was originally supposed to play a more substantial part in the film, stalking the characters for longer and leading them to believe it was the one responsible for their being on the planet. In another draft of the script, the creature was originally to have been found near a river and was barely seen, behaving almost like a ghost or apparition (it was from this draft that the creature earned its moniker). The River Ghost was initially conceived as a means to display the original, unused Predator design created for Predator by Boss Film Studios, although it was later decided to make the creature a completely original design. Despite this change of direction, the creature still bears some similarities to the original Predator design, most notably in the appearance of its head and its digitigrade legs. See more
