On the bedroom set, Jimmy was behind the camera. The set had a New England feel, with wainscoting and Shaker furniture. Out the windows were flats of green mountains. It was deliberately fake, Juhasz’s stylized idea of small-town American life.

“Have a seat, my pets,” Walter said.

“When he said ‘pets,’ he was talking about my balls,” Billy said. Maddy elbowed him hard.

“This is the most important scene in the film,” Walter said. “We must believe that Paul and Ellie are meant for each other. The sexual chemistry must be otherworldly.”

“All my sex is otherworldly,” Billy said.

In the scene, Ellie and Paul stumble up to the bedroom. From there, Walter’s stage directions read:

They kiss as they move into the bedroom. Paul kneels by the bed and puts his hand on Ellie’s breast. She unbuttons her blouse and removes her bra. He puts his mouth on her nipple. She unbuckles his pants, holds him. He pulls her skirt off. Eats her. She cums. He mounts her. She raises her legs to her ears and then moves to ride him. He lifts her in the air. She maintains her mount. She cums again. He explodes.

Maddy had been uncomfortable with Walter’s spelling of “cum” when she first read the screenplay but had figured Walter was trying to show that the sex needed to feel real, and hot, and urgent. “So here’s how we’re going to work,” Walter said. “We’ll rehearse it once. I’ll tell you how to move. You’ll both be dressed. This is just for the blocking, for camera. I want you to kiss. Everything else, you can suggest.”

Suggest. The death knell to the actor. Often “suggesting” was more uncomfortable than doing it. Bridget had come to the set and was standing near Walter. “The two of you will enter the room here,” Walter went on, indicating the door. “You’ll be kissing while you enter. Maddy, you’ll come in first, your back to the camera. So—just go for it.”

Billy and Maddy stood on the other side of the door and closed it. “Action on rehearsal,” Walter called. Billy leaned in and kissed her. It felt illicit because no one could see them doing it.

She hadn’t expected him to use tongue. His kiss was different from Steven’s, so much more welcoming. It was strange to be kissing Billy when Steven was in the building, a few hundred feet away. What if he had sneaked onto the closed set? The PAs wouldn’t stop him. But there was no time to worry, because Billy was pivoting her so her back was to the door, and then he pushed it open, moving with her into the room.

They shot the scene over several hours, in portions and out of sequence. Shortly before the lunch break, Walter began to get frustrated with her. She wasn’t sure what she was doing wrong, but he kept saying the sex felt “stagy.” He sat on the bed and said to Maddy, “I want you to play more. Not so serious. We need this to feel spontaneous, the first good sex she’s ever had. This time keep going until I say ‘Cut.’ We’ll get out before your first orgasm.”

“That’s always a good idea,” Billy piped up.

They got into position. Walter called action. Billy’s hands were rough on her nipples. She didn’t want to be responding, but she was, her nipples perking up. For this angle she was wearing the merkin, and he had on a nude jock cup, and as she rode the cup, she realized she was wet.

She rocked above Billy and saw something new on his face: surprise. Did he know? She had always heard that sex scenes weren’t sexy, but this was sexy, and maybe all sex scenes were, and she was conscious of the muscles on Billy’s body. Remembering Walter’s direction to keep going, she tilted her head, leaned down, and kissed Billy. Her tongue entwined with his. She was not herself, she was Ellie with Paul, and she had been unhappy in her marriage, and now this frightening man was making her feel things she hadn’t felt. They kept going, simulating the sex, and she wasn’t sure whether to continue, but it was a no-no to cut before the director did, so she kept riding Billy and she pretended to come, her back arching, her nipples exposed and alert, her mouth widening as Ellie cried out.

Finally, she heard “Cut.” She pulled up the covers. A wardrobe girl handed her the robe, and she slipped into it and sat on the bed.

Walter approached the two of them, a strange smile on his face. “Did you not hear me?” he asked Maddy.

“What do you mean?”

“I said ‘Cut’ a few minutes ago.”

“No!” Maddy spun to Billy. “Did you hear it?”

“Yeah,” he said. “But when you didn’t, I figured Walter would probably want us to keep going.”

“Bridget, did you hear?” she called.

Bridget nodded. “It’s okay,” she said. “That was the best one.” Maddy couldn’t believe she’d been so wrapped up in the scene that she’d lost her hearing, lost her sense of space.

“Please do not be embarrassed,” Juhasz said. “It’s good that you continued. You two were electric.”

Alone in her dressing room, she sat in a daze. She was not the kind of actress to lose her senses in performance. During plays she would hear sneezes, candy wrappers. She was always aware of her surroundings even in the moment. It was as though they had played a monstrous trick on her, wanting to embarrass her.

Steven worked late at Woodmere that night, a production meeting involving Bridget, Walter, and other key staff members. She crossed paths with him a few times, but he said he didn’t have time to talk.

When he arrived in the town house bedroom past midnight, he undressed silently, turning his back to Maddy. She put her hand on his shoulder and he jumped. “What is it?” she asked.

“I saw the dailies,” he said.

“Yes?”

“I could hear Walter saying ‘Cut,’ and you kept going. You were overheated to the point of deafness.”

“I was acting. It’s what I do.”

“You looked unprofessional.”

“I was just in the scene. You have to get past it, Steven. There’s a week more of sex scenes to go.”

“And I’m sure you’re looking forward to them.”

“What’s that supposed to mean?”

“Are you attracted to him?”

“He’s a good-looking guy. But I’m in love with you.”

“Maybe you should be with Billy instead of me.”

“I don’t know what you’re saying.” Out of all people, he had to understand what it was like to do a sex scene. “Come on, Steven. I shouldn’t have to explain this.”

“You disrespected me.” His lips were thin and old and she could see the shine on the lower one as she had at the Entertainer, when Kira postulated about his sexuality.

“Why are you being like this?”

“Because I care! You should know that jealousy is a sign of that. You said it on Torcello.”

“I know, but there’s nothing to be jealous of here—”

“Why did you do this to me?” His jealousy was so insecure and boyish. It wasn’t befitting of a powerful man. It seemed almost like an act. “Your only job was to get through the day professionally. And you failed.”

She dashed into one of the guest rooms and she sobbed into a pillow. She had imagined him leaving her many times, but not because she had performed too well in a role. Now he was going to end it, and when people asked what had happened, she would have to answer, “I didn’t hear Walter Juhasz call, ‘Cut.’ ” And they would laugh.

The irony was that she had no desire to be unfaithful. Their sex life was great, attentive, and playful. For a middle-aged man, his appetite was big; he was always hard and ready to go a second time. He said no other woman had turned him on this much. Whatever attraction she had to Billy, she didn’t want to act on it. The arousal had been chemical.

After she had finally stopped crying, she went downstairs, got her cell phone, and took it back into the guest room, closing the door. She held the phone in her hand as though not sure whom to call, but she knew she was tricking herself.

“Hi,” she said when Dan answered, and her voice must have been sniffly, because he said, “Are you okay?”

“Yeah. It was just a hard shooting day. I’m under too much stress, I think.”

“What happened?”

“Steven got jealous after a sex scene.”

“That’s moronic,” Dan said.

“It was maybe too much for him. It wouldn’t have been as bad if he weren’t producing.”

She fluffed up some pillows behind her head, remembering the long phone calls she and Dan used to have at the beginning, when he was courting her, when she fell asleep with the phone in her hand, or he did. “Are you sure you’re okay?” he said.

“I guess it’s a lot at once. First movie, starring opposite Steven, tons of sex. If it were one of the three, it would be enough.”

“I’m sure he’ll get over his jealousy,” he said. “He’s a professional.”

“Anyway,” she said, “tell me what’s going on with you. Are you in Savannah?” She had read in the trades that he’d signed on for another romantic weepie, The Inscription, also produced by Worldwide Films.

“Yeah,” he said. “It’s actually crazy that you caught me. I’m on a break right now.”

“I should let you go,” she said.

“No, I’m glad you called,” he said. “I thought we might be communicating through lawyers from now on.”

After her ill-fated coffee with Dan in the spring, she had taken the Nest assignment of rights to Edward Rosenman, who had worked out a collaboration agreement with Dan’s lawyer, the one he had hired after he fired the one who drafted the assignment. She would get costory credit on any version of The Nest that got made, and a third of any purchase price. She felt that the deal was fair to generous, but worried that Dan felt she had been greedy.
