Some of the scenes involving Angela floating on the hallways was taken from the first Night of the Demons (1988).
(at around 30 mins) Rick sarcastically refers to Terri (Christine Taylor) as "Marcia." Taylor would play "Marcia" in The Brady Bunch Movie (1995) a year later.
(at around 39 mins) Cristi Harris appeared topless in this film during a sex scene. In part 4 of Fango Flashback's "Night of the Demons" article series, Harris said when she took the role she knew there was nudity, but she was liberal and younger and didn't think it was a big deal. But on the day of shooting, she was a nervous wreck. The director told her they'd just do a quick shot and only shoot for a few seconds. So when the scene started, Harris pulled off her bra and tried not to panic. A few moments later, the director yelled cut and she quickly covered up. But when she watched the completed scene on screen, she was very embarrassed. The camera seemed to linger on her bare breasts forever. She said, "I learned fast how much footage could be made of a 'quick shot.'" After this, she went on to do several more films with topless sex scenes: Night of the Scarecrow (1995), Kiss of Death (1997), and Lurid Tales: The Castle Queen (1998).
Cristi Harris (Bibi), Zoe Trilling (Shirley), and Merle Kennedy (Melissa/Mouse) would go on to make uncredited cameo appearances in director Brian Trenchard-Smith's next straight-to-video horror sequel, Leprechaun 3 (1995).
