Netflix has now confirmed Helena Bonham Carter’s involvement, with the show’s Twitter account posting the official cast list, further announcing Jason Watkins will play Prime Minister Harold Wilson.
Several cast members have already been announced: Broadchurch star Olivia Colman will step in as Queen Elizabeth, with Vanessa Kirby seemingly confirming Helena Bonham Carter will play Princess Margaret, and Tobias Menzies announced as Prince Philip.
However, season 3 is arriving with a little bit of a shake-up, featuring a completely new central cast to reflect the passing of time.
Netflix’s The Crown has become one of the streaming giant’s centrepiece jewels: a lush, drama-filled examination of the events behind Buckingham Palace’s closed doors during Queen Elizabeth II’s reign.
