Perhaps Hitchcock's least remembered film from the American period, Under Capricorn continues to use the long edits premiered in Rope, but with less of a rigid aesthetic; there are some reaction shots interspersed and it employs multiple locations.
It has a reputation in France, but its melodrama failed everywhere else as audiences just didn't pay the babysitter to go and watch Hitchcock costume dramas. As a historical film, it's high on hokum, but it has an interesting, if preposterous story and the Australian setting is a novelty.
Ingrid Bergman has to act for her life to play an Irish alcoholic but whenever the film does catch fire, it's when she is on. Joseph Cotten broods effectively, but Michael Wilding seems to be impersonating Cary Grant more than a nineteenth century Irish aristocrat. His future wife Margaret Leighton is more interesting as a Mrs. Danvers style housekeeper.
But there are some diverting scenes, particularly a dinner party held by ex-murderer Cotten which the ladies of Sydney are too genteel to attend, broken up by a pie eyed Ms. Bergman. It's a rare Hitchcock film that has nothing to offer.
