The Spiral Staircase (1946)
Released in 1946 by RKO Radio Pictures, The Spiral Staircase arrived at a moment when Hollywood was finding its appetite for shadows. The postwar years had produced a run of crime pictures and psychological thrillers that leaned into moral ambiguity and visual darkness, and this film sits comfortably within that tradition, even as it reaches back toward the Gothic. The premise is stripped to its essentials: a stormy New England night, a grand and isolating house, a young woman who cannot speak, and a killer with a pattern. Based on Ethel Lina White's 1933 novel Some Must Watch (the same source that had already given Hitchcock The Lady Vanishes six years earlier), the story was adapted for the screen by Mel Dinelli, a writer who would go on to script Beware, My Lovely and who had a particular talent for confined, claustrophobic dread.
The director is Robert Siodmak, a figure whose career is worth pausing on for a moment. A German-born filmmaker who fled Europe in the 1930s, Siodmak had already made People on Sunday back in 1930 (a film I wrote about here, and one that shows how far he had travelled by the time he reached Hollywood) and would go on to become one of the key architects of American film noir. By 1946, with pictures like Phantom Lady and The Killers already behind him, he was at or near the peak of his Hollywood period. He brought to The Spiral Staircase a European sensibility about light, composition and silence that gives the film a texture you do not always find in studio thrillers of the era. For a companion piece from the same fertile late-forties period, see also The Reckless Moment (1949), another picture that uses a domestic setting to quietly unsettle.
The cast is a polished but mixed ensemble. Dorothy McGuire carries the central role of Helen, the mute servant, in a performance that asks her to communicate almost entirely through expression and physicality. Ethel Barrymore brings an imperious, bed-bound authority as the ailing matriarch, and her scenes have a theatrical weight that lifts the material. George Brent, Kent Smith and Rhonda Fleming round out a household full of people who may or may not be trustworthy, which is, of course, precisely the point. The film borrows freely from the conventions that would later calcify into the slasher genre, and genre historians often point to it as an early template for the killer-with-a-type formula. I also covered Blood and Black Lace (1964), Mario Bava's later and more lurid contribution to that lineage, which makes for an interesting comparison.
The craft on display here is, in certain departments, exceptional. Cinematographer Nicholas Musuraca, one of the great unsung technicians of the studio era, shoots the house and its surroundings with a quality of darkness that feels almost physical. His images favour pools of lamplight surrounded by genuine, pressing shadow, the kind of photography where what you cannot see feels as loaded as what you can. The score by Roy Webb is a brooding, orchestral piece that knows when to press and when to pull back, working in close concert with the visual atmosphere rather than against it. Harry Gerstad and Harry Marker share the editing credit, and the cutting in the film's early passages is notably controlled, letting tension build through withholding rather than acceleration. For a sense of how differently the horror genre could be handled in the same decade, my review of Dead of Night (1945) covers a British counterpart that plays similar games with dread from a very different angle.
The Spiral Staircase opens superbly, and then, somewhere around the halfway mark, rather lets itself down.
Those first forty minutes or so are excellent: taut, atmospheric and full of suspense, with cinematography that is the clear standout of the whole film. Robert Siodmak wrings a lot of menace out of shadow and silence, and early on this had me completely.
The trouble is that it does not sustain it. Around the midpoint the film shifts gears, settling from a crime and suspense piece into something much talkier, more of a drawing-room drama, and a lot of the tension bleeds away with it. The decision to make the heroine mute did not help me either; I can see what it is reaching for, but in practice I found it a frustrating device rather than an effective one, and it kept me at arm's length from a character I ought to have been gripped by.
The other oddity is that, for a film running a mere eighty-three minutes, it somehow manages to feel drawn out by the end. That is quite a trick, and not a good one. And yet, when the credits rolled, I came away more impressed than not.
The soundtrack is wonderful, the craft throughout is a cut above, and that opening stretch lingers long after the slower middle has faded. Three stars, a gorgeous-looking thriller that does not quite hold its nerve, but is well worth it for the first half alone.
The Spiral Staircase is the kind of film that reminds you how much of cinema's power lies in its first impressions, and how difficult it is to maintain what you have built. Siodmak and Musuraca between them produce images that genuinely linger, and Roy Webb's score gives the whole thing a tonal consistency that holds even when the script starts to drift. It is a film that earns its reputation on the strength of its atmosphere and its opening movements, and if it runs out of ideas before it runs out of minutes, that is a fairly common failing in the genre. Worth seeing, and worth rewinding.
