For which 1945 Alfred Hitchcock film did Dalí design the dream sequence?

Salvador Dalí designed the dream sequence for Alfred Hitchcock’s 1945 psychological thriller Spellbound.

The film stars Ingrid Bergman as psychoanalyst Constance Petersen and Gregory Peck as a man whose troubled identity and memories drive the mystery. Hitchcock wanted the dream scenes to look unlike conventional cinematic dream imagery, so producer David O. Selznick and Hitchcock brought in Dalí, whose precise yet disturbing Surrealist forms suited the material.

Dalí and Hitchcock conceived elaborate images involving distorted spaces, eyes, gambling imagery, and symbolic menace. The original filmed sequence was reportedly around twenty minutes, but Selznick considered it too long and complicated. Most of it was cut, leaving roughly two minutes in the released film; production designer William Cameron Menzies supervised the filming of the final version.

The key distinction is that Dalí designed scenes for Spellbound rather than directing the entire movie. The project is also often remembered as a landmark meeting between Hollywood suspense filmmaking and European Surrealism.
