Corrin will make her first appearance in the show’s fourth season rather than the upcoming third season as originally planned.
“Beyond excited and honoured to be joining The Crown for its fourth season,” Corrin said.
She continued: “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!”
“Emma is a brilliant talent who immediately captivated us when she came in for the part of Diana Spencer,” series creator Peter Morgan said. “As well as having the innocence and beauty of a young Diana, she also has in abundance the range and complexity to portray an extraordinary woman who went from anonymous teenager to becoming the most iconic woman of her generation.”
Many fans of the show took to Twitter to discuss the casting choice.
Season 3 of The Crown will launch later this year. In the upcoming season, Olivia Colman takes over the role of Queen Elizabeth from Claire Foy, and Tobias Menzies will play Prince Philip, the role previously played by Matt Smith.
Other Season 3 cast members include Helena Bonham Carter, Jason Watkins, Josh O’Connor, Emerald Fennell and Marion Bailey.
