Call me the hunter.
The first Predator was originally called Hunter until after production was completed. In the DVD commentary, director John McTiernan says Predator was originally pitched as Rocky vs. Alien, 'though he personally saw it as more like King Kong. In the 2001 short documentary "If It Bleeds We Can Kill It: The Making of Predator", brothers Jim and John Thomas said they got their script idea from a joke about Rocky IV. The gag was that Rocky had no one left to fight, so he may as well fight an alien.
