Season 3 of 'The Crown' dropped on Netflix yesterday.

The new season of 'The Crown' takes place in a whole new era with a brand new cast, depicting events that took place between 1964 and 1977. Olivia Colman replaces Claire Foy as Queen Elizabeth, Tobias Menzies plays Prince Phillip instead of Matt Smith, and Helena Bonham plays Princess Margaret after Vanessa Kirby played the role for the first two seasons.

Some of the key events of season three include the unmasking of the Queen’s art advisor Sir Anthony Blunt as a Soviet spy; the Aberfan disaster; the Apollo 11 moon landing; Harold Wilson’s two terms as Prime Minister; and Princess Margaret’s eight year-long affair with baronet and gardening expert Roddy Llewellyn.

Other characters and performances of note include Jason Watkins as Harold Wilson; Ben Daniels as Anthony Armstrong-Jones aka Lord Snowdon; Erin Doherty as Princess Anne; Josh O’Connor as Prince Charles; Emerald Fennell as Camilla Shand; and Charles Dance as Louis Mountbatten.

Fans set aside their entire Sunday to binge on the ten episodes of the new season.

People just couldn't stop watching.

There was high praise for the new cast on Twitter, even if Foy and Smith were missed.

Helena Bonham Carter's performance as Princess Margaret is being deemed iconic.

The Aberfan episode earned particular acclaim.
