"Castle Freak" went into production in 1994 after Gordon noticed art for the film in producer Charles Band's office. Gordon agreed to develop the film on Band's condition that the film take place in a castle, contain a freak, and would be shot on a very low budget. Gordon obliged as he would be able to cast who he wanted in the film and would get final cut. The film was shot in 1994 in a castle owned by Band in Italy, where Gordon had previously shot "The Pit and the Pendulum". The film was shot during a period when Full Moon Pictures was having financial issues and was released to little press on home video in November 1995.
