### Plot and setting
The film is set in a small New England town in 1906. Helen McCord, a maidservant mute since childhood after seeing her parents burned to death, attends a silent film on her day off while, upstairs in the theater, a lame girl is strangled, the latest victim in a series of murders of women with physical imperfections. Helen is the favored attendant of the bedridden Mrs. Warren, and the new physician Dr. Parry believes her condition may be curable by the psychological methods then being developed. As a storm isolates the Warren mansion, most of the household departs, and Helen discovers the secretary Blanche strangled at the bottom of the spiral staircase, realizing the killer is inside the house.[1](https://catalog.afi.com/Film/24977-THE-SPIRAL-STAIRCASE?cxt=filmography) • [2](https://www.tcm.com/articles/191478/the-essentials-the-spiral-staircase) • [6](https://tile.loc.gov/storage-services/public/gdcmassbookdig/newmoviesnationa1920nati-1946-02/newmoviesnationa1920nati-1946-02.pdf)
The killer is revealed in the final sequence to be Helen's employer's son, Professor Warren, who targets women he considers imperfect. Mrs. Warren shoots him, and Helen regains her voice in the aftermath.[7](https://www.commissionefilmcei.it/archivio-storico/la-scala-a-chiocciola/) A 1946 *New Yorker* review described the strangler as eliminating young ladies who did not measure up to his ideas of physical perfection.[8](https://www.newyorker.com/magazine/1946/02/09/1946-02-09-080-tny-cards-000018681)
## Production
The project began as one [David O. Selznick](https://www.edgepedia.org/david-o-selznick) picked up for [Ingrid Bergman](https://www.edgepedia.org/ingrid-bergman). When Bergman passed, Selznick sold the property to RKO under a partnership agreement with his Vanguard Films, furnishing the novel and the services of Schary, Siodmak, McGuire, and Barrymore in exchange for a share of the profits. The working titles were *The Silence of Helen McCord* and *Some Must Watch*.[1](https://catalog.afi.com/Film/24977-THE-SPIRAL-STAIRCASE?cxt=filmography) • [3](https://www.tcm.com/articles/417/the-spiral-staircase-1946)
**Adaptation changes.** White's novel was set in contemporary England; screenwriter Mel Dinelli and Schary moved the story to New England in 1906 for a more picturesque and threatening environment. Siodmak, a German émigré director then known for Universal thrillers such as *Phantom Lady* (1944), was loaned from Universal to RKO. His cinematographer was Nicholas Musuraca, formerly Val Lewton's camera chief on *Cat People* (1942), whose chiaroscuro lighting produced the film's expressionistic effects.[3](https://www.tcm.com/articles/417/the-spiral-staircase-1946) • [9](https://arts.columbia.edu/sites/default/files/content/PDFs/Programs/S22_Kit%20Noir%202022%20Program%20Book.pdf)
A well-known production detail concerns the killer's stalking eye in close-up: McGuire stated in a later interview that the eye shown, supposedly that of Professor Warren, was actually Siodmak's own.[1](https://catalog.afi.com/Film/24977-THE-SPIRAL-STAIRCASE?cxt=filmography)
## Reception
The film opened on 6 February 1946 to strong media reception and considerable audience interest; the *Washington Post* reported lines forming as early as 10 a.m. and capacity attendance on opening day. Reviewers positioned it as horror and praised Siodmak's use of genre devices such as thunder, candlelight, creaking doors, and gusts of wind, while newspapers and trade journals also commended the acting, direction, and production at a level above their expectations for a shocker. RKO's advertising leaned into this dual identity, quoting the *Hollywood Reporter*'s view that the film would take its place alongside anything in the "blood curdler" field while "sparkling with class from every angle."[10](https://ueaeprints.uea.ac.uk/26339/1/Tim_Snelson_-_Prestige_40s_horror.pdf)
It earned more than $1 million at the box office, made Siodmak's name in Hollywood, and helped Schary rise to head of RKO in 1947.[3](https://www.tcm.com/articles/417/the-spiral-staircase-1946)
## Legacy and later adaptations
Later critics have counted the film among the precursors of the modern slasher: film historians credit it, and films like it, with establishing elements such as the sinister killer with burning eyes, subjective point-of-view shots from the murderer's perspective, and the stalked vulnerable heroine.[11](https://torontofilmsociety.com/film-notes/the-spiral-staircase-1946-2/) Its theme of a killer eliminating women he deems imperfect has also been read as an allegory of eugenics and, given its timing, of the Nazis' wartime persecution of disabled people.[9](https://arts.columbia.edu/sites/default/files/content/PDFs/Programs/S22_Kit%20Noir%202022%20Program%20Book.pdf) [Turner Classic Movies](https://www.edgepedia.org/turner-classic-movies) calls it a blueprint for the standard gothic thriller, touching nearly every device of the genre in its 83 minutes.[2](https://www.tcm.com/articles/191478/the-essentials-the-spiral-staircase)
White's novel was adapted repeatedly after Siodmak's film: a 1961 NBC television version starring [Lillian Gish](https://www.edgepedia.org/lillian-gish), Gig Young, and [Eddie Albert](https://www.edgepedia.org/eddie-albert), directed by [Boris Sagal](https://www.edgepedia.org/boris-sagal); a 1975 British film starring Jacqueline Bisset and Christopher Plummer, directed by Peter Collinson; and a 2000 Fox Family Channel version starring Nicollette Sheridan and Judd Nelson, directed by James Head.[1](https://catalog.afi.com/Film/24977-THE-SPIRAL-STAIRCASE?cxt=filmography)
