Emma Corrin will play Lady Diana Spencer, who went on to become the Princess of Wales in Netflix’s The Crown. “Beyond excited and honoured to be joining The Crown for its fourth season,” Corrin said. “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!” Season 3 debuts later this year with Olivia Colman taking on the role of Queen Elizabeth from Claire Foy, and Tobias Menzies playing Prince Phillip, Matt Smith’s previous role.
