Fans of The Crown won't have to wait too much longer to see Olivia Colman take the throne once more.

The fourth season of the acclaimed royal biopic will hit Netflix on Sunday, November 15, the streaming platform confirmed on Thursday.

Netflix also revealed which points in the Royal Family's life the new series will focus on.

"As the 1970s are drawing to a close, Queen Elizabeth II and her family find themselves preoccupied with safeguarding the line of succession by securing an appropriate bride for Prince Charles, who is still unmarried at 30," a statement for the platform detailed.

"As the nation begins to feel the impact of divisive policies introduced by Britain's first female Prime Minister Margaret Thatcher, tensions arise between her and the Queen which only grow worse as Thatcher leads the country into the Falklands War, generating conflict within the Commonwealth."

News of the show's release date was accompanied by a new trailer for the fourth season, which offered a first glimpse at Gillian Anderson's portrayal of Thatcher.

The X-Files actress can briefly be spotted in a mirror and in Parliament in the teaser.

The trailer also contains the first appearance of Emma Corrin, who portrays Diana, Princess of Wales, in the new season.

The actress can be seen in a series of clips, both waving at crowds and in contemplative silence, before wearing the late royal's distinctive wedding gown.

"Something as important as the monarchy simply cannot be allowed to fail," the voice of Colman says in the beginning of the trailer.

The award-winning Netflix series charts Queen Elizabeth II's long-standing reign, from her formative years to the modern day.

Because it covers such a long stretch of time, actors and actresses are recast every two seasons, with Colman currently portraying the monarch in series three and four.

Tobias Menzies continues his role as Prince Philip, while Josh O'Connor plays Princes Charles.

The role of the monarch in the show was first forged by Claire Foy, and will be continued by Imelda Staunton in the fifth and sixth seasons.

It was announced last week that Jonathan Pryce has been cast as Prince Philip alongside Staunton, while Elizabeth Debecki will take over the role of Princess Diana from Corrin.

The final two series are expected to include the princess's death in 1997, which plunged the Royal Family into an annus horribilis.

Despite initially claiming the fifth season would be the last, show creator and writer Peter Morgan last month confirmed a sixth season would be forthcoming.

"As we started to discuss the storylines for series five, it soon became clear that in order to do justice to the richness and complexity of the story we should go back to the original plan and do six seasons.

"To be clear, series six will not bring us any closer to present day – it will simply enable us to cover the same period in greater detail," Morgan said in an interview with Deadline in July.
