Josh told Radio Times: “It’s the most famous breakdown of a marriage in history, and a lot of the accounts are from Diana’s side.
“I was keen not to play a villain. But what I’m pleased about is that in the last series people felt an affection for Charles, and a sympathy, and that was a really important foundation for telling this story.”
Josh went on to say the scripts for season four are “a tragic story of two people who loved each other and weren’t equipped to give the other person the thing they needed”.
“It’s beautiful and painful and poetic,” he said.
