If you haven’t heard about Mitford sisters, or if you are obsessed with them as much as I am - in either way watch this - it’s a fantastic piece of historical biography, shot in entertaining, purely British way. Their Wikipedia page basically tells you all you need to know before watching - loosely related to the Churchills, the 6 sisters were: "Diana the Fascist; Jessica the Communist; Unity the Hitler-lover; Nancy the Novelist; Deborah the Duchess and Pamela the unobtrusive poultry connoisseur".
