LIFEBOAT opens. Directed by Alfred Hitchcock. Written by Jo Swerling, from a story by John Steinbeck. Tullulah Bankhead, William Bendix, John Hodiak and Walter Slezak lead an impressive, ensemble cast in one of Hitchcock's lesser-known but enthralling, quasi-allegorical chamber piece/character study set entirely on a lifeboat carrying nine survivors of an Allied passenger ship's fatal mid-Atlantic encounter with German U-boat.
