The actresses who played the burns victims were dancers chosen because they were the same height as the actresses playing the victims, but significantly slimmer in build. This is because when the human body is subjected to burns it shrinks due to a loss of fluid.
The house used in this film is now the museum headquarters of the Atlantic Highlands Historical Society in New Jersey. It was falling into disrepair at the time of filming, and shortly after in 1980, the town condemned it and slated it for demolition. That's when the local historical society took action and purchased the property. It is now called the Strauss Mansion Museum, named for Adolph Strauss who had the house built in 1893. There are exhibits in every room, ranging from local history to Victorian displays. The restoration work is still ongoing after all these years due to the massive amounts of money (through donations) needed. However, the house is still there and not too much has changed. Some rooms are recognizable from the movie, while others maybe not because of display cases. The society usually shows the film in the house in October as part of their month of Halloween events. It is located at 27 Prospect Cir. Atlantic Highlands, NJ 07716
Star Dan Grimaldi didn't have to audition for the part of Donny Kohler. At the time, he was the lead in an Off Broadway play titled "Mama's Little Angels." The director and producers came to see it several times and ended up asking him if he was interested in doing their picture.
The film's original soundtrack turned out to be unusable, having been recorded on what actor Dan Grimaldi termed "less than up-to-date equipment." The soundtrack, in its entirety, had to be re-recorded and re-dubbed.
