Corrin was announced to play Diana in April 2019, to which she responded: "I have been glued to the show and to think I'm now joining this incredibly talented acting family is surreal," she revealed in a statement at the time.
"Princess Diana was an icon and her effect on the world remains profound and inspiring. To explore her through Peter Morgan's writing is the most exceptional opportunity and I will strive to do her justice!"
Alongside her in the role is her costar Josh O'Connor, who plays Prince Charles. In a late 2019 interview with Harper's BAZAAR U.S., O-Connor praised Corrin for her accurate portrayal of the late princess. "Emma's doing a brilliant job, and it's breathtakingly accurate; she looked the spitting image [of Diana], and it's kind of extraordinary, so that's kind of spooky."
Corrin won't return after season four, however. In The Crown's final two instalments, Diana will be played by Australian actress Elizabeth Debicki, which was announced on August 17.
The Crown season four will premiere on Netflix on November 15.
