If Joaquin Phoenix’s turn in 2013's Her as a man smitten by his virtual assistant teaches anything, it’s this: the only thing more fearsome than a haunted Alexa is a horny one. According to Scarlett Johansson (who voiced Samantha, the AI who Phoenix’s character Theodore falls in love with), filming a simulated sex scene between the odd duo was “so gross” that Phoenix fled the set.
During a conversation with Dax Shepard and Monica Padman’s “Armchair Expert” podcast, Johansson recalls Phoenix struggling to keep it together after an initial take of the scene, which involves Samantha virtually orgasming while Theodore has intercourse with a sex surrogate. It’s an uncomfortable scene to watch—and apparently, even more uncomfortable to shoot.
