The Favourite (2018) online

THE FAVOURITE is a bawdy, acerbic tale of royal intrigue, passion, envy and betrayal in the court of Queen Anne in early 18th century England. At the center of the story is the Queen herself (Olivia Colman), whose relationship with her confidante, adviser and clandestine lover Sarah Churchill, Duchess of Marlborough (Rachel Weisz) is turned upside down by the arrival of the Duchess's younger cousin Abigail (Emma Stone). Soon the balance of power shifts between the women as they jockey for influence with the Queen and the court.
