10 Hidden Gem '80s Slasher Horror Movies
3. The Undertaker
Not to be confused with the seven-time WWE World Champion, The Undertaker is a hidden gem for a wide variety of reasons - most notably for how long it really did stay hidden.
In that regard, The Undertaker never received a theatrical release, nor did it receive a VHS release, and supposedly the only finished copy of this Franco Steffanino feature belonged to star Joe Spinell. When Spinell passed away shortly after the movie was completed in 1988, the film became somewhat of a white whale for horror hounds, with various bootleg versions eventually surfacing.
2016 would finally see The Undertaker recut and restored for a Blu-ray release, and the movie can nowadays be found on certain streaming services, including Prime Video. It may not be the greatest of films, mind, but this is one worth seeking out solely for how long it was impossible to find.
As for the plot, it's a largely paint-by-numbers affair as Spinell plays an undertaker with a penchant for killing young women. Some of the acting is pretty painful in parts, and the editing is a little ropey in places, but again, The Undertaker deserves a spot on this list due to its unique spot in slasher history.
