After the death of her young daughter to cancer, Penny Knatchbull is encouraged by the Duke of Edinburgh to take up carriage driving as a way of coping with her grief. At the same time, Princess Diana is dealing with her own kind of grief - being trapped in a loveless marriage - and so when approached via an intermediary to cooperate with journalist, Andrew Morton, on a book exposing the truth about her marriage, she agrees. But knowing how explosive the book will be, Diana must have total deniability regarding any involvement. In this episode Edith Bowman talks with Movement Coach and Choreographer Polly Bennett, Head of Research Annie Sulzberger, Director Jessica Hobbs, and the actor playing Prince Philip in Season 5, Jonathan Pryce.  The Crown: The Official Podcast  is produced by Netflix and Somethin’ Else, in association with Left Bank Pictures.
