Emma Corrin said she was "moved" by Prince Harry's comments on The Crown, which he made during his interview with James Corden.
The Duke of Sussex said: "I am way more comfortable with The Crown than I am seeing stories written about my family or my wife. That is obviously fiction, take it how you will. But this is being reported on as fact because you're supposedly news. I have a real issue with that."

Following his statement, Emma, who plays Princess Diana in the series and who won a Golden Globe for her performance, said during a virtual "backstage" event after the ceremony: "I felt incredibly grateful to him, actually, and incredibly moved by what he said."
She added: "Certainly the way he spoke about it, and the fact that he's watched it, and the fact that obviously I played his mother and that would have been such a sensitive thing, I was very moved by the fact that he acknowledged it."
