An excerpt from Sharon Stone's upcoming memoir, "The Beauty of Living Twice," was published by Vanity Fair on Thursday, and the passages described some shocking treatment at the hands of movie producers.

In one of the exploitative incidents described by Stone, an unnamed producer asked her to have sex with a male costar on an unnamed movie in order to improve their onscreen chemistry.

Stone wrote that "he explained to me why I should f–k my costar so that we could have onscreen chemistry."

She said the producer boasted to her about making love to Ava Gardner on-screen back in his day, but the "creepy thought" of him in the same room as Gardner gave her "pause."

Stone continued: "You guys insisted on this actor when he couldn't get one whole scene out in the test … Now you think if I f— him, he will become a fine actor? Nobody's that good in bed."

"I felt they could have just hired a co-star with talent, someone who could deliver a scene and remember his lines. I also felt they could f--- him themselves and leave me out of it. It was my job to act and I said so," Stone wrote.

Stone said that she did not sleep with him, but that the actor did make "a few haphazard passes" at her. She also said that this was not the only time a producer told her to sleep with a costar.

"I've had other producers on other films just come to my trailer and ask, 'So, are you going to f--- him, or aren't you? … You know it would go better if you did,'" Stone wrote.

Stone said that she always refused, but that this refusal led her to be considered "difficult." In another passage, Stone wrote that one of her former managers told her that no one in the industry would hire her because she wasn't "sexy."

She wrote: "I wasn't, as they liked to say in Hollywood at the time, 'f---able.'"

The "Basic Instinct" actress also discussed the behavior of an unnamed director who she referred to as a "#MeToo candidate." Stone said that the director wanted her to "sit in his lap and take direction."

When she refused this, he refused to shoot with her.

Stone also discussed her big break, "Basic Instinct," and described how it almost broke her after she first saw that infamous scene in the movie.

"The Beauty of Living Twice" will be released on March 30.
