Lifeboat(1944)
Submitted by Don P
A Hitchcock classic from a story by John Steinbeck set entirely in a lifeboat.
During WWII, the survivors of a torpedoed ship murder the U-Boat Captain they allowed aboard after they learn he induced William Bendix to jump overboard.
They spare the German Sailor they pick up near the end of the film and are eventually rescued.
Look for the Hitchcock cameo in the newspaper advertisement for Reduco Obesity Slayer.
