With Will Rogers Jr. as his dad, Jane Wyman as Betty Rogers and heaps of homespun warmth, there's plenty to like about this biography of the "Poet Lariat" who never met a man he didn't like. From its lead performance to its storyline based on Betty's reminiscences to its fond direction by Michael Curtiz (a polo-playing buddy of Rogers), the movie has an authenticity befitting this most authentic of American heroes. Humorist, vaudevillia
