Think the new season of The Crown is dramatic as hell? Well apparently behind-the-scenes was quite the shitshow too, as Emma Corrin was reportedly hospitalised after filming a scene.

The actress who portrays Princess Diana revealed in a new interview that while filming the pool scene in Spain, she had to be rushed to hospital.

“I’m asthmatic and I had been ill for a while with a bad cough,” she told Glamour Magazine. “I had to film a scene in a freezing-cold swimming pool, with the kids playing William and Harry. It was honestly the hardest scene to film because I was genuinely keeping myself alive treading water, and also keeping five-year-old ‘Harry’ alive, as we found out he couldn’t swim!”

Emma continued, “We were meant to be flying back that night to the U.K., so we went past a hospital to get me antibiotics. The doctors gave me an oxygen test and said, ‘We cannot let you go because your oxygen levels are so low,’ so I was hospitalised.”

She went on to reveal that hospital staff were The Crown stans and they knew she was filming for the Netflix series, so they offered to be discreet during her time there.

“We know you’re playing Princess Diana, would you like us to put a cardboard bag over your head so no one recognises who you are?” a hospital staff member offered her.

She went on to discuss Diana’s icon status, stating that she finds the description to be “quite reductive” to the late royal.

“I find the word icon, particularly in reference to Diana and with any woman we put on a pedestal, to be quite reductive,” she said. “The label of icon ignores so much of who Diana was and her beautiful complexity. She was called the People’s Princess because people felt like they could relate to her. That is so much more important than any kind of label.”

The brand new season of the royal drama premiered on Netflix over the weekend and it’s already making a splash across the globe.
