When the time came to transform into Princess Diana, Corrin had jitters. "Initially I was very daunted, very much listened to the noise, heard all the voices, and got quickly frustrated and quite scared about it and thought, ‘This isn't actually giving me anything to work with," she told E! News. "So then I very much had to put blinkers on and just do my own thing."
Corrin continued, "I realized this is a character that I'm playing. This is The Crown's version of Diana. I can bring a lot of what I want to do with this part. Everything that resonates with me. That really changed it for me. It doesn't remove the pressure and the responsibility that I feel, but it made it more manageable to do the role."
During an interview with Radio Times, according to People, she revealed that Diana's battle with bulimia was a storyline she insisted the writers explore. Corrin said, "We'd been working on her body language, and we put together a document that we sent to the script team and said: 'Can you include some of this in the writing because we'd love to really flesh out those scenes?'"
Corrin continued, "I felt that if we were trying to depict bulimia in an honest way, we had to actually show it—otherwise it's a disservice to anyone who has been through that," she said. "I don't think we should shy away from those conversations; Diana was very candid about her experience with bulimia, and I so admire that."
Not so much. "I try not to think about it because I think it's kind of a slippery slope," she told E!. "I don't know whether they will or they won't watch it. I hope that if they do they enjoy it and appreciate our performances as exactly that—as performances, as interpretations of people who are in the public eye. But I hope that they also don't watch it if they don't want to because understandably it's hard."
To really get Corrin into character, the costume department made sure to get all of her looks as close to the real thing as possible."We almost see Diana's entire journey throughout season four," assistant costume designer Sidonie Roberts said in a press kit interview. "We start at the very beginning and see her evolve from a young girl living with her friends in Sloane Square to the makings of a princess, then actually becoming the 'People's Princess,' to finally the beginnings of the end, which we will see more of in season five."
Roberts added, "I think despite the obvious changes, there is a real sense, or arc, of the same person throughout all these stages in terms of how she dresses. There is and always was a sense of playfulness, an openness, and with that a vulnerability that connects her to her image."
According to Roberts, Corrin was nothing but a pro when it came to using the clothes for her characterization. She "completely understood just how integral clothes are to Diana's character and therefore the importance of her costumes for season four and our work," Roberts said. "So, with that said, from the very get-go she was so invested in the most excited, enthusiastic and committed way that it was a real joy for us working together with her."
