Brian DePalma directs Margot Kidder, Jennifer Salt and William Finley in this surreal thriller where a reporter investigates a murder she witnesses in a detached Siamese twins’ apartment.

A pretty deranged piece of filmmaking contains layers of Hitchcock pastiche, bravura split-screen tension tests, loopy arthouse dream sequences and a nonsense punchline ending. The chief pleasure is Kidder’s typically unhinged performance – 4 parts sexy to 1 part oddball. The thriller aspects are the least loved components and DePalma blurts them out like a hungry child forced to say grace. This is still more akin to his Sixties experimental hippie work than his slick, playful shock fests. A likeable transition.
