Actor Kevin Brophy (Peter) said in an interview that he still has the purple cape that he wears in the movie and that he has worn it every Halloween since making the film.
The majority of the movie was shot in three locations. The outside of Garth Manor was shot at a mansion in Redlands, California. The inside of Garth Manor was filmed in a residential home in Pasadena, California. The frat party was filmed in an apartment lobby in Los Angeles, California. The mansion used as Garth Manor is now a museum. The owners made the change shortly after filming was completed.
Though there were several shots of actors running from the front of the house to the front gates, the distance between the two is actually one mile.
Future director Frank Darabont had one of his earliest film credits on this movie, as a Production Assistant.
