The hero of this film is a boy named Harry Potter Jr, who is surrounded by a fantasy world of witches, wizards, trolls, and magic, 11 years before J.K. Rowling's Harry Potter novels swept the publishing world.
Director John Carl Buechler had been so impressed with Noah Hathaway's performance in "The Neverending Story" that he cast him as the lead in the film.
In John Carl Buechler's original story treatment, Torok was a monster who was systematically killing off the inhabitants of the building slasher-movie style. Producer Charles Band however wanted to create a PG-13 movie so the story was altered and the fantasy element created.
Julia Louis-Dreyfus has admitted being embarrassed by her role. In April 2013 Jay Leno showed her scene as a nymph on Episode #21.125 (2013). Louis-Dreyfus was surprised and visibly annoyed that Leno dredged up her connection to the film.
