Grad-level geeks will also recognize the references to Sam Fuller's Shock Corridor, Vincente Minnelli's The Cobweb, and Val Lewton's Isle of the Dead.
It’s fun, in a film-school kind of way, to pick out the references: “Out of the Past,” “Laura,” “Isle of the Dead,” and so forth.
It is a dazzling pastiche of a Hollywood movie of the 1940s and 50s, part Gothic horror in the Val Lewton mode of Bedlam and Isle of the Dead and part noir- thriller in the psychiatric cycle that stretches from Hitchcock's Spellbound to Samuel Fuller's Shock Corridor, complete with the obligatory dream sequences, expressionist gestures, throbbing undercurrents of guilt and anxiety and bold narrative twists.
