The Emmy-winning show, created by Peter Morgan and launched in 2016, tells the story of Britain's late Queen Elizabeth’s reign against the backdrop of various royal dramas.

"Mixed emotions. On the one hand it's been a lot of work, so I'm tired. But on the other hand, it's been a family that I've lived with now and worked with for ten years," Morgan said as he walked the red carpet at London's Royal Festival Hall.

"Well, it's bittersweet always. It has been an extraordinary experience to work on for everybody, I think," said actor Lesley Manville. "But I'm so proud of the work in this final season."

Actor Gillian Anderson said that every actor who worked on it said it was their "favourite job." Adding that it had "a really lovely, warm, respectful, grown up feel about it."

The second part of the final season starts streaming on Dec. 14. Its first four episodes, focusing on Princess Diana's final days in 1997, were released in November and Part 2 is made up of six episodes. Actors Imelda Staunton and Dominic West reprise their roles as Elizabeth and Charles, with Ed McVey and Meg Bellamy taking on the roles of William and Kate.

The Queen, who died in Sept. 2022, while the season was being filmed, is at the heart of the final episodes, the show's makers said.

Part 2 picks up some months after Princess Diana's death, with the royal family reeling from the tragedy. In happier scenes, it sees William starting university and meeting his future wife, Kate, and Charles marrying Camilla.
