Scarlett Johansson admitted Joaquin Phoenix was so upset while filming 'bizarre' orgasm scene that he left set

Cast your minds back about a decade ago and the movie Her was being released.

The film told the story of Theodore Twombly (Joaquin Phoenix), a man who falls in love with artificial intelligence Samantha (Scarlett Johansson).

Since the movie released there have been plenty of warnings about the danger of becoming too enthralled by AI but it doesn't appear to be stopping us from tumbling headfirst into a false world scraped together by stealing the efforts of real creators.

Johansson herself has also ended up turning down offers to give her voice to actual AI and not just fictional depictions of them.

Deciding she didn't want to be the voice of a ChatGPT system as she 'just felt it went against my core values', Johansson said she was 'shocked, angered and in disbelief' when OpenAI released a voice which sounded strangely like her.

However, when she was working on Her there was apparently a moment where Phoenix ended up walking out and it was while she was recording some noises for a very particular scene in the movie.

Speaking to Dax Shephard's Armchair Expert podcast, Johansson explained that while shooting the movie she had to record sounds of her having an orgasm.

Phoenix had already filmed the scene and was watching her do the vocals for it, but according to Johansson, he ended up getting uncomfortable and left.

She said: "We tried to get through one take, and he was, like, losing it.

"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 theatre and I'm in this box, and he was like staring at me, and the lights are low, and Spike [Jonze] is there… it was so bizarre."

However, Johansson said she was alright to record the sounds but asked if her co-star could return as she said 'I need him to come back'.

"I was fine. Joaquin was not - he was so upset about it," Johansson continued.

"He left the studio, and now I’m in this box by myself, and I’m like, 'I can’t do it alone. I need him to come back'.

"He needed a break; he took a break, and he came back in.

"You don’t want to hear your voice ever. You definitely don’t want to hear what you sound like having an orgasm. Ew. It’s so gross. It was so bizarre."

To be honest that's a fair verdict, perhaps this is one of the reasons why a lot of actors don't like watching back their old stuff.
