The Haunted House of Horror

The Haunted House of Horror, also titled Horror House and The Dark, is a 1969 British horror film directed by Michael Armstrong and starring Frankie Avalon and Jill Haworth as young adults looking for a thrill by spending the night in an old mansion in the English countryside. The film's tagline was "Behind its forbidden doors an evil secret hides!" Plot In swinging London, a group of twenty-something friends are attending a rather dull party, and they decide to gather for kicks at an old, supposedly haunted mansion where one of their number used to play as a child. Among the group is American ringleader Chris, his bored girlfriend Sheila, promiscuous Sylvia (who has her eye on handsome two-timing Gary) and his "good girl" date, Dorothy. Also tagging along are nervous, heavy-set Madge, her sarcastic, hot-tempered boyfriend Peter, sweet-faced Richard and his friend Henry. They are all followed by Paul Kellet, Sylvia's older, jealous and married ex-boyfriend. They have fun exploring the mansion, even holding a séance before separating one by one by candlelight on the moonlit night. Sylvia, frightened by the mansion, leaves and hitchhikes toward home, but Kellet hangs behind at the mansion. While all the partiers are alone, Gary is brutally knifed and his body is discovered by the panic-stricken Dorothy and the others. Because some of them have a criminal record, Chris convinces the group to leave Gary's body far from the home and to pretend that Gary left and that no one knows where he went. They are all shaken by Chris' assertion that one of them must be the murderer. During the next few weeks, the survivors are possessed by tension and guilt, and after Gary is reported missing, they are further shaken by questioning from the police. Kellet confronts Sylvia, learning that she may have lost a lighter that could link them to the mansion. He returns there but is also killed.
