Unfairly overlooked by those expecting a signature Hitchcock thriller, Under Capricorn is nevertheless an accomplished and effective film. Particularly skillful is the way Hitchcock starts off at the surface of his characters and gradually penetrates into their minds, where grave emotions and obsessions lurk, some noble and some quite dark. The film has psychological depth and moral ambiguity that even many of Hitchcock's other films do not have, and the result is an undercurrent of uneasy tension that wraps us up in the characters.
