In her first statement after being announced in the role, Corrin called Diana "an icon" and expressed her excitement to be joining the cast. "Beyond excited and honoured to be joining The Crown for its fourth season. 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!"
