In Dial M for Murder, Hitchcock shoots an entire film on one set. In Rope, he not only just uses one set, he also experiments with long takes…using only 5 or 6 takes to complete a full-length feature. Where did he get these ideas from…? Well, in 1944, four years before Rope and ten years before Dial M For Murder, there was Lifeboat. Based on a John Steinbeck story, this film takes place IN A BOAT at sea. A ship has gone done (it happens before the movie even begins) and we see Tallulah Bankhead in a small-ish dingy, adrift. As the film progresses, more and more people find their way to the lifeboat, including a German, who might or might not be captain of the ship that bombed the American ship, sinking it. For an hour and a half, this film deals with the way these people all get together and relate with each other and the impending doom they face if not rescued. A well done, thought provoking film…that is more drama than thriller, but tense enough to be something from The Master of Suspense.
