One of the main secrets to staying young is staying healthy. I've sometimes had to suppress a smile when some young lady, who has obviously not taken care of herself through diet or exercise, says admiringly, 'Ooh, I hope I look as good as you do when I'm your age!' Although it's intended to be complimentary, it's actually a back-hander.
I never thought I was particularly good looking. But when I see old photographs, I realise that I was. I do wish I had known that at the time because beauty is power. I didn't realise how lucky I was to be young, beautiful and in Hollywood. It didn't hit me. Every day I woke up, went to the film studio and just got on with it.
I used to not be confident. My father certainly didn't add to my confidence. When I was 17 or 18, I was voted the most beautiful girl in England by the association of press photographers. When they called Daddy for a comment, he said, 'I'm amazed. She's a nice looking girl, but nothing special.'
I used to go over to Gene Kelly's house and play volleyball, and Paul Newman and Marlon Brando were always there. You kind of took it for granted because I was 20, 21, 22, and they were a bit older - well, Gene certainly was. But it was just part of daily living. They were in the same profession, and you didn't think that much about it.
