Helena Bonham Carter once had a sleepover at Windsor Castle

The Crown actress, along with her then-partner Tim Burton, Rachel Weisz and her husband Daniel Craig, spent the night at the royal residence “about 10 years ago” and even had a tour of the building given by Queen Elizabeth and her husband Prince Philip.

She said: “It’s fun! Rachel Weisz was there with James Bond. I stayed in Prince Charles’s rooms. We had supper and the Queen and Prince Philip gave us a tour.”

The visit was made even more special by the fact that each guest was given something from the royal archive that had a connection to them, with Alice in Wonderland director Tim presented with a first edition of Lewis Carroll’s classic fairytale and Helena – who portrayed the Queen Mother in The King’s Speech – given a letter from King George VI’s speech therapist.

She added in an interview with Radio Times magazine: “They’d found something from their archive that each of us would appreciate.

“So Tim had the first edition of Alice in Wonderland, I had a letter from Lionel Logue, who was the King’s speech therapist.

“It was really touching.”

The 53-year-old star plays the queen’s late sister, Princess Margaret, in the new series of The Crown and has previously admitted that she spoke to the royal – who died in 2002 – via a medium before taking on the role

And Helena has also admitted that the spirit told her to perfect her smoking technique.

She said: “I asked her via a medium! Oh, she has a great sense of humour. She reminded me to be neat and get my smoking right. It’s true – I’m barking!”
