Dame Helen Mirren has disclosed that she wrote to the Queen to warn that she would be playing her on film, saying: "I hope it's not too awful for you".
The actress was about to portray the monarch in The Queen, the 2006 dramatisation of Britain's reaction to the death of Diana, Princess of Wales.
The film recalled the aftermath of the princess' death, when the public clamoured for a public show of mourning from the royal family. The Queen was heavily criticised for staying away from London for several days, and there were calls for the flag at Buckingham Palace to be flown at half-mast.
"I realised that we were investigating a profoundly painful part of her life, so I wrote to her," Mirren said.
"How do you write to your queen? Was it, 'Madam' or 'Your Highness' or 'Your Majesty'? I said, 'We are doing this film. We are investigating a very difficult time in your life. I hope it's not too awful for you.'
"I can't remember how I put it. I just said that in my research I found myself with a growing respect for her, and I just wanted to say that."
The Queen did not reply.
"She didn't write back, of course, but her secretary did. You know, 'Yours sincerely, da di da di da,' on behalf of the Queen. I was very relieved subsequently that I had written that letter."
Mirren's disclosure was reported in a Radio Times piece written by Lord Bragg, who interviewed her for an episode of the South Bank Show.
She won an Oscar for The Queen in 2007, dedicating the award to the monarch in her acceptance speech.
'Terrible' clothes
However, she told Lord Bragg that she burst into tears at the prospect of wearing costumes based on the monarch's "terrible" clothes.
"I cried, I really did, when I first saw them. Not so much, 'do I have to wear them?' but, 'do I have to play someone who would wear clothes like this?'
"But they were so beautifully made. And they showed the Queen had no vanity at all. She is happiest grabbing a shirt, pulling on another terrible cardigan, a tweedy skirt, comfortable shoes and a rain mac and she's off," the actress said.
Mirren, 76, has previously said that she believed the film had been "seen and appreciated" by the Queen. The Duke of Cambridge and Duke of Sussex had also watched it and were "cool" with it.
The actress has also spoken in the past about being invited to tea with the Queen and the Duke of Edinburgh.
She told a Hollywood seminar in 2019 that the tea party had comprised "Prince Philip, the Queen, a sheikh of somewhere or other and a couple of horsey people".
In a "lesson in embarrassment", she wanted to ask the Duke of Edinburgh to pass the milk jug, but forgot how she had been told to address him.
"I mean, is it 'Sir'? Is it 'Your Majesty'? Is it 'Your Highness?'" Mirren said. "Is it rude to ask him to pass the milk? Or should I just ask for a lackey?
