Gordon stated the film was shot quickly; originally approached in January to direct, Gordon was shooting the film by June. "Castle Freak" was shot in Italy at a castle owned by Charles Band, which Band had bought years earlier. Gordon had shot "The Pit and the Pendulum" in the same castle four years earlier. According to Jonathan Fuller's film diary, filming was underway until July 1994. His diary states that on July 7, 1994 the crew were a day and a half behind on their shooting schedule. On July 8, 1994, Charles Band arrived at the castle with his wife and father, stating that they were to finish filming by July 9.
