Inquisition (Spanish: Inquisición) is a 1976 Spanish-Italian historical horror film written and directed by (and starring) Paul Naschy. It also features Daniela Giordano, Julia Saly and Mónica Randall. The film was shot in May and June 1976, and first shown in Spain in 1978. The special effects were handled by Fernando Florido, who outdid himself with his elaborate design for the demon Belphegor, seen during the film's bizarre dream sequence. Daniela Giordano loved the film and thought it was one of the best projects she ever worked on. An Argentinian one-sheet exists with the name of the film as Bajo el terror de la Inquisicion / Under the Terror of the Inquisition, but there is no evidence that the film was ever shown there theatrically.Although the film was completed in 1976, it wasn't shown in Spain until 1978. The film was dubbed in English in 1976 (the intended "international version"), but it was never shown theatrically outside of Spain. The English-dubbed print was eventually sold directly to Home Video in the 1980s. The film has since been released in English on Blu-ray by Mondo Macabro.
