If you haven't already make sure you watch Brideshead revisited.

You have Phoebe Nicholls (who played Lady Rose's mother) and Diana Quick (Polina Molotova in The Death of Stalin and the Queen in the eponymous BBC series) doing some similar social machinations in the background of an absolutely stacked period-drama with a cast including Jeremy Irons, Laurence Olivier, and John Gielgud.
