Krasna had written a serious play, The Man with Blond Hair, which received a tepid response. He said that Moss Hart suggested he write a commercial comedy instead along the lines of Junior Miss. Krasna based the family in the play on that of Groucho Marx, who was a good friend and occasional collaborator. The play was named in honor of Krasna's first wife, Ruth.
