"Psyche '59" opened at an art theatre in New York City in 1964. Receiving lukewarm reviews, it closed quickly, and was then used as a co-feature in neighborhood theatres. I consider it a near-masterpiece. Starring Patricia Neal, Curt Jurgens, and Samantha Eggar, it is a spellbinding study of a woman suffering from hysterical blindness, her sex addict husband, and her younger sister, who it seems was sexually imposed-upon at a young age, and who is both cruelly nymphomaniacal and masochistic as a result. This film was clearly ahead of its time.
The screenplay by Julian Zimet, from a novel by Francoise des Ligneris, is a finely-nuanced piece of work.
Alexander Singer might be considered a great director of films about women's issues, as well as a great director of actresses. Consider his direction of Lola Albright in "A Cold Wind in August" three years before, and his direction of Lana Turner in "Love Has Many Faces" the year following. The fact that all three of these films were failures is clearly the reason why Singer is not widely known ("Love Has" having failed simply because its critics and audiences could not appreciate its deliberately melodramatic style).
The cinematography in "Psyche '59" is outstanding. One shot, in which the camera manages to look upward towards Samantha Eggar, while she is lying on the sand, took my breath away. Within the context of the scene, this use of strange camera angle was intensely effective, and not at all pretentious. Whether it was Singer's idea, or that of cinematographer Walter Lassally, I guess I'll never know.
The only flaw in "Psyche '59" is that the actress in the role of the grandmother seems too young for the part.
