"I had a producer bring me to his office, where he had malted milk balls in a little milk-carton-type container under his arm with the spout open."

"He walked back and forth in his office with the balls falling out of the spout and rolling all over the wood floor as he explained to me why I should fuck my co-star so that we could have onscreen chemistry. Why, in his day, he made love to Ava Gardner onscreen and it was so sensational! Now just the creepy thought of him in the same room with Ava Gardner gave me pause. I watched the chocolate balls rolling around, thinking, You guys insisted on this actor when he couldn’t get one whole scene out in the test … Now you think if I fuck 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 fuck him themselves and leave me out of it. It was my job to act, and I said so. This was not a popular response. I was considered difficult."
