Season Four of The royal drama, starring Olivia Colman, will drop on the streaming service on November 15. The Crown is a historical drama web television series about the reign of Queen Elizabeth II, created and principally written by Peter Morgan, and produced by Left Bank Pictures and Sony Pictures Television for Netflix. It grew out of Morgan’s film The Queen (2006) and his stage play The Audience (2013), and is credited as based on the latter. The first season covers the period from Queen Elizabeth and Philip, Duke of Edinburgh’s marriage in 1947 to the disintegration of her sister Princess Margaret’s engagement to Group Captain Peter Townsend in 1955. The second season covers the period from the Suez Crisis in 1956 to the retirement of Prime Minister Harold Macmillan in 1963 and the birth of Prince Edward in 1964. The third season spans the period between 1964 and 1977, including Harold Wilson’s two periods as prime minister, and introduces Camilla Shand. The fourth will include Margaret Thatcher’s premiership and introduce Lady Diana Spencer. The fifth and sixth seasons, which will close the series, will cover the Queen’s reign into the 21st century.
