While filming a scene in a dark parking garage, the opaque contact lenses Brinke Stevens wore as Lilith hampered her vision. She missed a step on the stairs, badly injuring her ankle. After icing the injury for awhile, she shot the scene anyway, not wanting to delay production. The next day, her ankle was swollen so much she needed crutches.
The film's trailer reuses music from Stuart Gordon's The Pit and the Pendulum. The music in turn, was originally composed by Cristobal De Morales.
Brinke Stevens and Debbie Rochon were supposed to fly to Delaware to shoot a werewolf movie in 2001, but it was postponed. Full Moon then grabbed them both to star in this.
As of 2021, this is the final entry in the Witchouse franchise.
J.R. Bookwalter originally was open to making a Witchouse 4 but the proposed fourth entry never took off.
