“He called me to his office. He had these very low ’70s, ’80s couches, so I’m essentially sitting on the floor, when I should have been on set,” Stone said on the “Louis Theroux” podcast Monday.\

“And he’s running around his office in sunglasses explaining to me that he slept with Ava Gardner and I should sleep with Billy Baldwin, because if I slept with Billy Baldwin, Billy Baldwin’s performance would get better, and we needed Billy to get better in the movie because that was the problem.”

Stone, now 66, said Evans believed sleeping with Baldwin, now 61 and married to Chynna Phillips, would give the pair better “chemistry on screen,” which would “save the movie.”

“The real problem with the movie was me because I was so uptight, and so not like a real actress who could just f–k him and get things back on track,” she said.

“The real problem was I was such a tight arse.”

The “Casino” star admitted she was frustrated that the filmmakers had not listened to her suggestions on whom to cast instead of the “Bio-Dome” actor — like Michael Douglas.

“I didn’t have to f–k Michael Douglas,” she said.

“Michael could come to work and know how to hit those marks, and do that line, and rehearse and show up.

“Now all of a sudden I’m in the ‘I have to f–k people’ business.”

Stone first shared the uncomfortable situation in her 2021 memoir, “The Beauty of Living Twice,” but did not name Evans or Baldwin at the time.

“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 f–k my co-star so that we could have on-screen chemistry,” she wrote in the tome.

“Now you think if I f–k 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.”

“It was my job to act and I said so,” she wrote.
