Ghoulies IV is an American film written by Mark Sevi and directed by Jim Wynorski. It was first published in 1994.
In the final installment, Jonathan Graves (Peter Liapis) returns, this time a retired-occultist-turned police officer. His latest assignment finds him battling his former girlfriend Alexandra (Stacie Randall), who has escaped an asylum and tries to summon forth the demonic forces Graves trifled with in the first film.
The film also stars Barbara Alyn Woods.
The series' fourth and final entry was directed by Jim Wynorski, made by CineTel Films and also released straight-to-video in 1994 by Columbia TriStar Home Video. Original Ghoulies lead Pete Liapis returned to the series as Jonathan Graves, now a detective who must deal with a new pair of Ghoulies. This entry in the series has been criticized by the fans of the series because the 'Ghoulies' in this film are completely different, however in recent years the movie has managed to receive a cult following for its humor and originality; instead of the usual puppet Ghoulies, the movie cast little actors in costumes. Ghoulies IV was released on DVD in 2007 by Echo Bridge Home Entertainment.
