Not long after marrying Hackett, the couple settled in Hollywood in the late 1920s to write the screenplay for their stage success Up Pops the Devil for Paramount Pictures. In 1933, they signed a contract with MGM and remained with them until 1939. Among their early assignments was writing the screenplay for The Thin Man (1934). They were encouraged by director W.S. Van Dyke to use the writing of Dashiell Hammett as a basis only and to concentrate on providing witty exchanges for the principal characters, Nick and Nora Charles (played by William Powell and Myrna Loy). The resulting film was one of the major hits of the year, and the script was considered to show a modern relationship in a realistic manner for the first time.[citation needed]
