why did Laurence Olivier hate her?
I don’t think he hated her. He was rather frustrated with her. He once said (before they started working on The prince and the showgirl)
‘One thing was clear to me. I was going to fall most shatteringly, in love with Marilyn. She was so adorable, so witty, and more physically attractive than anyone i could imagine’ - Laurence Olivier
So you can definitely tell that he was very smitten with her. Unfortunately their working techniques were very different. Her Method acting was the opposite to his rather laissez-faire attitude.
He once said that in his opinion ‘She is a brilliant comedienne, and therefore an extremely good actress’ but this changed quickly after he told her on set “All you have to do is be sexy, dear Marilyn”. After that statement nothing was the same and Marilyn lost all her respect for Olivier. He then called her ‘a professional ameteur’.
Rumors have it that he wanted to have an affair with her as well and because it didn’t work out he got bitter. He also saw an opportunity to revive his career by playing opposite the famous Marilyn Monroe.
In retrospective and many years later Olivier had nice things to say about her
‘She gave a star performance. Maybe I was tetchy with Marilyn and with myself, because I felt my career was in a rut…I was as good as I could be, and, Marilyn! Marilyn was quite wonderful, the best of all. What do you know?’ - Laurence Olivier
