The Crown season 4 trailer is here and it teases the start of Prince Charles (Josh O'Connor) and Princess Diana's (Emma Corrin) tragic marriage. Netflix's critically acclaimed British series is gearing up for its latest season, which will debut new cast members including Corrin as Lady Diana Spencer. The arrival of the former Princess of Wales means the show will expectedly do a deep dive into how her entry to the Royal Family shook the monarchy, while also tackling her troubled relationship with Charles.

Principal cast members from the previous seasons of The Crown are also returning, led by Olivia Colman as Queen Elizabeth, Tobias Menzies as Prince Philip,  Helena Bonham Carter becomes Princess Margaret, and Ben Daniels as her husband, Antony Armstrong-Jones, Lord Snowdon. That said, as the show moves forward in time, the focus will shift to the younger generation of royals. This is indicative in the new trailer for The Crown season 4 with the spotlight clearly on Princess Diana and her impending marriage to Prince Charles.

Posted by Netflix, The Crown season 4 trailer chronicles Diana's entry to the British Royal Family. Clocking in at one minute and 45 seconds, the video features a narration that talks about fairytales as it builds towards the much-anticipated recreation of the 1981 royal wedding, which was watched by over 750 million people around the world. Watch The Crown season 4 trailer below:

Prior to the release of the new trailer, Netflix had rolled out promotional stills of Corrin as Princess Diana, as well as, Gillian Anderson who will play Margaret Thatcher in The Crown season 4. The trailer also featured a glimpse of the next Prime Minister, including what seems to be her first audience with Queen Elizabeth. Heavily leaning on the romantic relationships of the show, there are also glances of a miserable-looking Princess Margaret and a tense encounter between Prince Philip and the Queen. That said, it's clear Netflix is putting the focus on Diana, as Corrin's iteration takes up the majority of the screen time in the video.

Depending on the pacing of events in The Crown season 4, it's possible that the upcoming year will hinge on the royal wedding and the immediate events that lead up to it. While the trailer features a considerable amount of happy instances between Prince Charles and Princess Diana, which include the engagement, there are also hints of troubled times, although it's unclear whether these take place before or after they've tied the knot. If anything, there are two more seasons left before The Crown wraps up, meaning they have enough time to do a deep dive into the years following the pair's fairytale wedding. In the meantime, season 4 will more likely tackle the massive event from different points of view with a shot of Charles obviously petrified on the day of his wedding. It's also interesting to see how the royal family will react to the public's overwhelmingly positive response to Diana.
