December Noir—”The Spiral Staircase” (1945) (d. Siodmak, w/ Dorothy McGuire, George Brent and Ethel Barrymore)
If Hitchcock didn’t draw on this for “Psycho,” I’ll eat my hat. So. Many. Elements. Big gothic house with frail, old, MEAN lady living upstairs. Overhead shot of staircase. Voyeurism followed by murder of undressing blonde. Disappointing son. Stuffed birds. And more!
