Helena Bonham Carter says she used a psychic to seek Princess Margaret's blessing for her role on The Crown

The Guardian

The actress said at the Cheltenham literature festival over the weekend that to prepare for the Princess Margaret role, she spoke to her relatives and consulted an astrologer, a graphologist and a psychic. “She said, apparently, she was glad it was me," said Carter. "My main thing when you play someone who is real, you kind of want their blessing because you have a responsibility...So I asked her: ‘Are you OK with me playing you?’ and she said: ‘You’re better than the other actress’ … that they were thinking of. They will not admit who it was. It was me and somebody else."
