Continuity mistake: At the beginning of the film when Georgiana is talking with her mother about her engagement, the curl running down the back of Georgiana's neck disappears and reappears multiple times.
Question: Why did the Duke refuse to divorce Georgiana and marry Bess, as Georgiana herself even suggested? They lived in the 1700s. Henry VIII divorced multiple wives in the 1500s. It was possible for a nobleman to end a marriage if he wished.
