Actor D. J. Williams (1868-1949) appears unbilled early on as a Lord at The Queen mother's table
In reality, King Christian VII was only 17 when he became betrothed to 15-year-old cousin Princess Caroline Matilda, sister of George III of the UK, who was unaware that the bridegroom was mentally ill. So the two were mere teenagers when they married at Christiansborg Palace on November 8, 1766. After his marriage, Christian became very sexually promiscuous and soon became involved with courtesan Støvlet-Cathrine. The neglected Caroline Matilda became involved with Dr. Johann Struensee, who was the King's personal physician. Struensee became the de facto ruler of Denmark but was soon deposed and executed. The King divorced Caroline Matilda in 1772 and she died in Germany of scarlet fever on May 10, 1775, age 23. So although Christian lived until age 59, all action in this film would have historically taken place between very young people.
According to a review in the Motion Picture Herald (February 16, 1935), some scenes for this British production were shot at the Amalienborg Royal Palace in Copenhagen.
