According to Scarlett Johansson, Joaquin Phoenix had a difficult timerecording audio for their sex scenes in Spike Jonze’s 2013 film Her.

During Johansson’s appearance Monday on the 500th episode of Dax Shepard’s_Armchair Expert_ podcast, the Academy Award nominee, 37, said that her costarhad already filmed the entire movie before she replaced Samantha Morton in thevoice role and scenes needed to be re-recorded.

She said that recording sex scenes between the artificial intelligenceSamantha, who falls in love with Phoenix’s Theodore Twombly, was “one of themost challenging jobs that I’ve done,” and recording sessions with Jonze, 52,proved uncomfortable for Phoenix, 47 .

“He was like angry… he had already [filmed the scene]he had done it in person,and now he was with me in this weird theater and I’m in this box, and he waslike staring at me, and the lights are low, and Spike is there… it was sobizarre, Johansson continued.

“I was fine. Joaquin was not – he was so upset about it,” she added. “He leftthe studio, and now I’m in this box by myself and I’m like, ‘I can’t do italone. I need him to come back.’ He needed a break; he took a break and hecame back in.”

the Black Widow star admitted during the episode that she spent a lot oftime around adults as a child, which she attributed to her Manhattanupbringing and career and said that she “definitely was in differentsituations that were not age-appropriate.”

“Luckily my mom was really good about protecting me from a lot of that stuff,but she can’t do that for everything,” Johansson told the pair.

Johansson said that this perceived maturity went hand-in-hand with her being”hyper-sexualized” as a young actress, despite saying that sex was “never ahuge part of my actual personality.”

“Because I think everybody thought I was older and I’d been [acting] for along time and then I got kind of pigeonholed into this weird hyper-sexualizedthing,” Johansson said. “It was like, that’s the kind of career you have.These are the roles you’ve played and I was like, ‘This is it, I guess.'”

Shepard and Johansson also acknowledged that this “hyper-sexualized”pigeonhole in Hollywood has an early expiration date for women.

“The runway is not long on that and so it was scary at that time,” the_Marriage Story_ actress recalled. “And I attributed a lot of that to the factthat people thought I was much, much older than I was.”
