During World War II, Lazar, with Benjamin Landis, suggested to the U.S. Army Air Forces that it produce a play to encourage enlistment and to raise funds for the Army Emergency Relief Fund. The Air Forces commanding general, Henry H. Arnold, agreed and the play "Winged Victory" was written by Moss Hart and produced by Hart and Lazar. It was a huge success, playing on Broadway and on tour around the U.S. for over a million people. A film version was produced during the same period.
