Some believe “Old Dark House” thrillers began with J.B. Priestley’s 1927 novel Benighted, which was adapted for the screen by James Whale as The Old Dark House in 1932. The reality is that the template had already been created by Mary Roberts Rinehart in her 1908 novel The Circular Staircase, which she reworked into a highly successful 1920 Broadway production entitled The Bat with playwright Avery Hopwood. Author and actor John Willard also had a Broadway smash hit with his 1922 play The Cat and the Canary, which shared a number of familiar horror/mystery elements with Rinehart’s creation, most significantly the gloomy mansion in an isolated setting with a menacing character prowling the corridors.
