Finding good roles became increasingly a concern. Kate O'Brien dramatized her historical novel "For One Sweet Grape" into "That Lady", set in the Spain of Philip II. A swashbuckling romance, the play was not well received. In 1951, Cornell played the lead in Somerset Maugham's comedy, "The Constant Wife" for a summer festival in Colorado. The play, starring her longtime favorite Brian Aherne, was produced again in New York and grossed more money for the production company than any other play.
