In regards to the filmmaking, this is one of Hitchcocks greatest achievements. I love the small setting (only a lifeboat), dialogue and acting. Tallulah Bankhead beautifully plays a laid back shipwreck survivor; she steals the show ,and the dialogue somehow keeps you involved into what seems like, at first glance, a boring movie. It is important to note that this movie is different than other Hitchcock films, it's not as tense and thrilling as others such as psycho or even The 39 Steps. That being said, it's still definitely worth a watch because of its unique setting, filmmaking and its psychological questions of morality.
