Deep woods slasher inspired by the success of Halloween (1978) while predating Friday the 13th (1980) camp/forrest setting. Directed and produced by porn filmmakers, filming of The Prey began in October 1979 and completed in early 1980. The movie was eventually shelved and then released in 1983. For the international market about 15 minutes of footage (without the consent of the director) was added (gypsy backstory and various sex scenes).
Notorious for including over-long and unnecessary nature footage, The Prey borderlines Z-Film territory, is filled with improvised dialogue and is quite entertaining if you're into unintentional humor. That said, The Prey finally made its blu-ray debut (skipping a DVD release) with three different versions of the film and plenty of bonus material.
A good bad movie worth checking out.
