* ActingForTwo: A minor example. Jonathan Breck, who plays the Creeper, also appears as the bald cop towards the end of the film.
* DevelopmentHell: The third film was stuck here for years, not least because of certain ugly issues about the writer/director's past.
* EnforcedMethodActing: Creator/JustinLong and Gina Phillips didn't see the Creeper truck for the first time until they were on-set. In addition, Jonathan Breck made sure he didn't meet either of them until they were all on-set together.
* RealitySubtext: Victor Salva, the director, was previously arrested for performing sex acts on underage boys. The first film in particular makes for a much different watch with this knowledge.
* TheOtherDarrin: Minor example, the Creeper in the last scene of the movie is actually Creator/JustinLong, not Jonathan Breck.
* WhatCouldHaveBeen: Gina Philips was asked to cameo in the second movie.
** There were talks for a prequel showing the Creeper hunting in the Wild West era, but this never came to pass.
