The Forgotten (also known as Don't Look in the Basement and Death Ward #13) is a 1973 independent horror film directed by S. F. Brownrigg, written by Tim Pope and starring Bill McGhee, former Playboy model Rosie Holotik, and Annabelle Weenick (credited as Anne MacAdams) about homicidal patients at an insane asylum.

The nurse finishes packing and is attacked by Harriett, a patient who accuses her of stealing her "baby" (a plastic doll).

Callingham indicates to Charlotte that it was Masters who cut out her tongue, apparently to prevent the elderly woman from disclosing the secret.

During the confrontation, she implies that Masters used to be a real doctor, but was fired after killing a patient; this psychotic break led to her being institutionalized.

Sam then leads Charlotte to the basement, where a man grabs her ankle, and she responds by beating him to death with a toy boat.

Shortly thereafter, the film was acquired for theatrical distribution by Hallmark Releasing, a sub-distributor for American International Pictures located in the New England area.

In July 1973, they test-marketed the film under a number of new titles, including The Snake Pit, Beyond Help, and Death Ward No.

The movie received a nationwide release under this title in August 1973, and Hallmark continued to program the film throughout the remainder of the 1970s, often issuing it as part of double or triple bills with other titles such as The Last House on the Left, The House That Vanished, and Let Sleeping Corpses Lie, which Hallmark released in the US as Don't Open the Window.

The film was released five separate times in 2003 by Diamond Entertainment, Platinum Disc, Pop Flix, and Alpha Video respectively.

It was released both as a single feature by Video International in 2008 and as a part of a five-disk movie pack by Echo Bridge Home Entertainment in 2010.

Mill Creek re-released the film one more time in 2013, for their three-disk "American Horror Stories: 12 Movie Collection".

The running time was truncated to less than 80 minutes; still, it was branded as a Video Nasty, and though it escaped prosecution, was effectively a 'banned' title.

[4] Cavett Binion of AllMovie gave it a generally favorable review, writing, "somehow the intrinsic sleaziness generated by the threadbare production manages to lend it a remarkably suitable ambience.

Brownrigg does manage to convey a sense of seedy claustrophobia during the depraved proceedings.”[6] Almar Haflidason from BBC gave the film three out of five stars.

[7] While it was omitted from Phil Hardy's The Aurum Film Encyclopedia: Horror, replaced with a review for Don't Look Now, the earlier edition, The Encyclopedia of Horror Movies (Harper & Row, 1986) provided a favorable review: "What lifts the film out of the usual run of asylum movies is its creation of a claustrophobic, hermetically sealed world and a powerfully unremitting ambience of craziness.

Added to this are the inmates themselves, each hopelessly enmeshed in with their own obsessions and unable to communicate with the outside world but each also representing distinctly recognizable, identifiable, facets of humanity, though seen through a frighteningly distorting prism -- the judge consumed with guilt, the man who believes he is an army sergeant, a girl whose maternal feelings become fixated on a doll and so on.

In March 2017, former horror punk guitarist from the Misfits, Doyle Wolfgang Von Frankenstein,[10] was put to star in Death Ward 13, a remake and continuation of Don't Look in the Basement, to be directed by Todd Nunes (All Through the House) and produced by The Readmond Company.
