- Colbert Bump: The series as a whole got much more attention after The Spoony Experiment did a review of the second movie's ... interesting... video game adaptation.
- Hey, It's That Guy!: Noteworthy horror alumni appear throughout the series, specifically Linnea Quigley, Kane Hodder, Tom Woodruff Jr., R.A. Mihailoff, and Doug Bradley. And of course, there's Lance Henriksen.
