Lombard was just doing her patriotic duty. Barely a month after the surprise attack on Pearl Harbor, she was selling war bonds in her home state of Indiana. Wanting to get home quickly to husband Clark Gable, Lombard convinced her mother and several others to board a plane back to California. It crashed outside of Las Vegas, killing the screwball comedy bombshell at the age of 34. Her final role, in Ernst Lubitsch's To Be or Not To Be, is considered to be one of her finest.
