Background: Francis was born in Oklahoma City, Oklahoma Territory (present-day Oklahoma) in 1905. Her parents, Joseph Sprague Gibbs and his actress wife Katharine Clinton Francis, had been married in 1903; however, by the time their daughter was four, Joseph had left the family. Francis inherited her unusual height from her father, who stood 6 feet 4 inches. She was to become Hollywood's tallest leading lady (5 ft 9 in) in the 1930s.
Context: In the spring of 1925, Francis went to Paris to get a divorce. While there, she was courted by a former Harvard athlete and member of the Boston Bar Association, Bill Gaston. Kay and Bill saw each other only on occasion; he was in Boston and Kay had decided to follow her mother's footsteps and go on the stage in New York. She made her Broadway debut as the Player Queen in a modern-dress version of Shakespeare's Hamlet in November 1925. Francis claimed she got the part by "lying a lot, to the right people". One of the "right" people was producer Stuart Walker, who hired Kay to join his Portmanteau Theatre Company, and she soon found herself commuting between Dayton, Indianapolis, and Cincinnati, playing wisecracking secretaries, saucy French floozies, walk-ons, bit parts, and heavies.  By February 1927, Francis returned to Broadway in the play Crime. Sylvia Sidney, although a teenager at the time, had the lead in Crime but would later say that Kay stole the show.  After Kay's divorce from Gaston, she became engaged to a society playboy, Alan Ryan Jr. She promised Alan's family that she would not return to the stage - a promise that lasted only a few months before she was back on Broadway as an aviator in a Rachel Crothers play, Venus.  Francis was to appear in only one other Broadway production, a play called Elmer the Great in 1928. Written by Ring Lardner and produced by George M. Cohan, the play starred Walter Huston. He was so impressed by Francis that he encouraged her to take a screen test for the Paramount Pictures film Gentlemen of the Press (1929). Francis made this film and the Marx Brothers film The Cocoanuts (1929) at Paramount's Astoria Studios in Astoria, Queens, New York.
