Douglas began dating Joan Crawford during the filming of Our Modern Maidens. They got married on the 3rd of June, 1929 at City Hall in New York City. Douglas was underage and therefore added one year to his birth year, changing it to 1908. Joan Crawford took off three years from her age so that they would have the same year of birth registered. After their marriage while in London, Douglas became active in society and politics while Joan remained busy with her career and became involved with Clark Gable. Douglas and Joan divorced in 1933. Regardless of their divorce, Douglas remained on friendly terms with Joan throughout her life.
