One of the photos by Lawrence Schiller is the last nude photo ever taken of Ms Monroe, taken just two days before her death.
The love scene called for Monroe to be in bed as Gable walks into the bedroom to kiss her.
The producer, Frank Taylor, thought that it was so groundbreaking and extraordinary that a major mainstream actress would do that, he saved it.
Monroe, who was battling a crippling depression, anxiety and low self-esteem, was under the round-the-clock care of a psychiatrist.
The one thing that she was rock solid in, with her lack of confidence, she knew that her physicality was pleasing to people, that people liked to look at her, and people liked to look at her body.
She always wanted people to like her.
