The Forgotten (1973 film)

The Forgotten is a 1973 American horror film directed by S. F. Brownrigg in his directorial debut, written by Tim Pope, and starring Bill McGhee, Rosie Holotik, and Annabelle Weenick (credited as Anne MacAdams). Its plot focuses on a young nurse, Charlotte Beale, who takes a job at a rural sanitarium plagued by a series of mysterious murders.

An independent production, The Forgotten was filmed over twelve days in Tehuacana, Texas. It was originally released independently in May 1973, before Hallmark Releasing Corporation and American International Pictures (AIP) acquired it for theatrical distribution. Hallmark and AIP issued the film under several alternative titles before settling on Don't Look in the Basement. It was distributed under this title beginning in July 1973, and continued to screen at theaters and drive-ins throughout the 1970s, often paired with The Last House on the Left (1972), The House That Vanished (1973), and Let Sleeping Corpses Lie (1974), the latter of which was issued under the title Don't Open the Window. The film was a sleeper hit, grossing $1 million in theatrical rentals after its first several years of release.

A sequel, Id: Don't Look in the Basement 2, was directed by Brownrigg's son, Anthony, and released in 2015.
