Princess Diana's storyline will be included
Princess Diana will be played by British actress Emma Corrin.
"Beyond excited and honoured to be joining The Crown for its fourth season," Corrin said in a statement released by Netflix.
"I have been glued to the show since the first episode and to think I'm now joining this incredibly talented acting family is just surreal. Princess Diana was an icon, and her effect on the world remains profound and inspiring. To be given the chance to explore her through Peter Morgan’s writing is the most exceptional opportunity, and I will strive to do her justice!”
And from the sounds of the the cast and crew's reaction to her wearing a replica of Princess Diana's wedding dress, she did. In early September 2020, Corrin opened up about what it was like to wear the recreated wedding dress made by the original gown's actual designers.
"The Emanuels, who designed the original, gave us the patterns, and then it was made for me," Corrin said. "We were filming the scene when you first see her in the wedding dress—I think it was Lancaster House in London—and I had a team of about 10 people helping me put it on, because it's massive."
However, once Corrin finally stepped out in her full costume, the room was speechless. "I walked out and everyone went completely silent," she said.
Gillian Anderson will play Margaret Thatcher
Anderson confirmed her role in season 4 via the official The Crown Twitter account, writing in a statement, "I am so excited to be joining the cast and crew of The Crown and to have the opportunity to portray such a complicated and controversial woman." "
Thatcher was undoubtedly formidable but I am relishing exploring beneath the surface and, dare I say, falling in love with the icon who, whether loved or despised, defined an era."
Prince Charles will play a major role in season 4
Josh O'Connor, who joined as the role of Prince Charles in season 3, has hinted at the Prince of Wales being a key storyline going forwards.
"I think this [season], you're right, it's very much the Diana and Charles years, and particularly focusing on what happened there and the ramifications of that going forward," he told Vulture.
The Crown will come to an end after season 6
Although the show had been slated finish after five seasons, creator Peter Morgan surprised fans when he announced in July 2020 that The Crown season 6 was happening.
"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," creator Peter Morgan said in a statement, per Deadline.
"To be clear, Series 6 will not bring us any closer to present-day - it will simply enable us to cover the same period in greater detail," he said.
There is a teaser for The Crown season 4
While no official full-length trailer has been released just yet, Netflix did drop a teaser trailer in late August, and if it's any sign of things to come, season four is going to be every bit worth the wait.
