Entertaining dark comedy with a high vomit quotient. Bits of the history are correct; most of it is wrong or imaginary. We don't know whether Queen Anne had lesbian relations with either Sarah or Abigail; the portrayal of Abigail as a proto-Beck Sharp doesn't correspond with the evidence; Harley was not at all the satyr-like figure portrayed in the film (more like Henry St John, who doesn't appear); the stuff about Sarah being drugged, falling off a horse and ending up in a brothel is fictitious; the terms 'Prime Minister' and 'Leader of the Opposition' are anachronistic; and so on. But it's a good movie.
