Adrienne Barbeau (Adult Christine) used the same wig she wore in Swamp Thing (1982).
Mo was supposed to be a photographer and even wears a camera around her neck throughout the film. All shots of her using the camera were cut.
Leftover sets from Leprechaun 5: In the Hood (2000) were used to film scenes inside the convent.
The location used as Christine's house was actually across the street from the location used for the sorority house.
Megahn Perry (Mo) and Joanna Canton (Clorissa) knew each other before they were cast. They grew up in the same town and even dated the same guy.
