She made a movie with Marilyn, 1953 “How to Marry a Millionaire”, she was well acquainted with Marilyn and she said the following about her.
She sure registered on that screen. The minute the camera turned on her she became this incredible creature, and she was absolutely dazzling. She was-there’s no question about that. During our scenes she’d look at my forehead instead of my eyes. At the end of a take, she’d look to her coach for approval. If the headshake was no, she’d insist on another take. A scene often went to fifteen or more takes. Despite this I couldn’t dislike Marilyn. She had no meanness in her- no bitchery. She just had to concentrate on herself and the people who were there only for her… Fifty years on, we’re still watching her movies and talking about her. That’s not a dumb woman- trust me.
