AceShowbiz - Actress Emma Corrin had to be hospitalised for oxygen treatment after shooting a suffocating scene for "The Crown" in a Spanish swimming pool.
The young star portrays the late Diana, Princess of Wales, in the new season of the hit Netflix show and recalls a gruelling shoot in Spain that culminated with a surprise health scare ahead of her flight back home to the United Kingdom.
"I'm asthmatic and had been ill for a while with a cough," Emma tells Glamour U.K. of the scary incident. "I had to film a scene in a freezing cold swimming pool. It was the hardest scene to film because I was genuinely keeping myself alive treading water."
"We were meant to be flying back that night to the U.K. and went past a hospital to get antibiotics. The doctors gave me an oxygen test and said, 'We can't let you go because your oxygen levels are so low' so I was hospitalised."
And then things got really weird for Emma as staff realised who she was and what she was doing in Spain.
"I remember the nurses figuring out what I was filming and saying, 'Would you like us to put a cardboard box over your heard so nobody recognises you?' " she laughs.
Emma had been recreating the real-life 1983 tour of Australia Princess Diana took with her then-husband Prince Charles, portrayed by Josh O'Connor, during her filming stint in Spain.
