The gold and jewel encrusted gown worn by Jodhi May (as Lady Sarah) to the court of the newly crowned George III was previously worn by Helen Mirren as Queen Charlotte in The Madness of King George (1994).
The beaded necklace Geraldine Somerville (Lady Emily) wears during the scene in which her character reads a letter from her son, who is at Eton, is the same necklace Kate Beckinsale (Emma Woodhouse) wears when she sings with Frank Churchill at Randalls in Emma (1996).
