Devil's Nightmare (French: La plus longue nuit du diable, lit. 'The Devil's Longest Night', Italian: La terrificante notte del demonio, lit. 'The Terrifying Night of the Demon') is a 1971 supernatural horror film directed by Jean Brismée and starring Erika Blanc, Jean Servais, Daniel Emilfork, and Lucien Raimbourg. Its plot follows a group of tourists who spend the night in a historic castle owned by a family plagued by curses and Satanism. <br /><br />Plot: <br />Undoubtedly, evil comes in many forms. With this in mind, the unholy stain of a silent, irrevocable curse weighs on the eerily vacant castle of the former World War II German general, Baron von Rhoneberg. For decades, a dark pact has been keeping the baron alive; however, now that a group of seven unsuspecting tourists has ended up in the ancient, memory-laden mansion of evil, unseen forces set in motion a bloody ballet of temptation, human weaknesses, and sin. Now, a mysterious, beautiful enchantress takes over, taking great pleasure in toying with the doomed visitors' unspoken desires. But Satan has all the time in the world. Is there an escape from the Devil's longest night? <br />Credits: <br />Erika Blanc as Lisa Müller <br />Jean Servais as Baron von Rhoneberg <br />Daniel Emilfork as Satan <br />Lucien Raimbourg as Mason <br />Jacques Monseau as Father Alvin Sorel (as Jacques Monseu) <br />Colette Emmanuelle as Nancy <br />Ivana Novak as Corinne <br />Shirley Corrigan as Regine <br />Frédérique Hender as Nurse <br />Lorenzo Terzon as Howard <br />Christian Maillet as Ducha <br />Maurice De Groote as Hans (as Maurice Degroot) <br /><br />Directed by Jean Brismée <br />Screenplay by Patrice Rhomm <br />Story by Pierre-Claude Garnier (as Charles Lecocq) <br />Patrice Rhomm <br />Produced by Pierre-Claude Garnier (as Charles Lecocq) <br />Zeljko Kunkera <br />Claudio Rainis <br />Cinematography André Goeffers <br />Edited by Panos Papakyriakopoulos <br />Music by Alessandro Alessandroni <br />Production companies <br />Compagnie Europeenne Television et de Cinema <br />Delfino Film <br />Distributed by Ciné Vog Films (Belgium) <br />Albatross Cinematografica (Italy) <br />Release date November 14, 1971 <br />Running time 94 minutes <br />Countries Belgium, Italy
