She said: ‘My lips are sealed on that subject. I’m not going to go on national TV and say what I think about Meghan and Harry because look what happened to you.’
Dame Joan also recalled the advice given to her by Marilyn Monroe upon her arrival in Hollywood as a young woman.
‘She said: “Beware of the wolves in Hollywood honey because if they don’t get what they want they will cancel your contract.”,’ the actress revealed.
‘The casting couch, which I never, ever, ever did. I probably would have been a lot more successful. Can you imagine how much more successful I would have been?’
Dame Joan recalled being invited to meet a film producer in New York aged 25 only to find him undressed in a bath.
‘There was an air of misogyny,’ she said.
‘That was the world, and for a lot of young girls at that time, particularly if you were good looking, it was tough.’
