Trivia: In real life, Georgiana was only nine years younger than her husband, the Duke. She was seven years older than Charles Grey. The film portrays her as being much younger than her husband and closer in age to Charles.

Trivia: In real life, Mary secretly married her second husband, William Stafford, while Anne was still Queen. Henry and Anne did not approve because Stafford had a low social rank and little money. Mary was banished from court, and her parents and uncle disowned her. Her final interaction with Anne was probably when Anne sent her a golden cup and some money, but still would not allow her at court. She was probably not present at the execution of Anne, like in this movie.
