Netflix Drops First Trailer For 'The Crown' Season 4

You can watch it below:

The trailer kicks off with Olivia Colman (as The Queen) explaining: "Something as important as the monarchy simply cannot be allowed to fail."

Meanwhile, the trailer then flicks to a first look at Emma Corrin (who plays Princess Diana in Season 4) and viewers get a glimpse of the princess' breathtaking wedding dress.

The best bit? We've finally got a release date, too. It's 15th November, guys - mark it in your diaries!

Season four of the royal drama will be the last for the current cast, which also includes Tobias Menzies as Prince Philip and Helena Bonham Carter as Princess Margaret.

They will then pass the baton to a new set of royals, including Imelda Staunton who will take on the role of the Queen, Lesley Manville as Princess Margaret and Elizabeth Debicki as Princess Diana.

The fourth season picks up in the late 1970s and will depict much of Prince Charles and Princess Diana's romance. As Netflix explain: "Charles' romance with a young Lady Diana Spencer (Emma Corrin) provides a much-needed fairytale to unite the British people, behind closed doors, the Royal family is becoming increasingly divided."

Fans will also be introduced to Gillian Anderson's portrayal of Margaret Thatcher and viewers will watch as tensions arise between her and the Queen, which as Netflix explains "only grows worse as Thatcher leads the country into the Falklands War, generating conflict within the Commonwealth."

Last month, more good news was announced for The Crown fans. Netflix confirmed the show will run for six seasons, instead of five - as previously thought.

"News from the palace: we can confirm there will be a sixth (and final) season of @TheCrownNetflix, in addition to the previously announced five!" The streaming platform tweeted.

"Writer/creator Peter Morgan: 'As we started to discuss the storylines for Series 5, 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.'"

I think we can all agree 15th November cannot come soon enough. If you need to refresh your memory in the meantime, the first three seasons are available to stream on Netflix now.
