Anders Danielsen Lie's full-frontal nude scene was included to show the female gaze, director Joachim Trier revealed. He said, "It was important to show because we are making a film about a young woman and her gaze. Sex scenes are often filmed from a male point of view. Not many male directors are aware of that. I think girls should be allowed to have some eye candy too." He said Danielsen Lie was pretty sporty about it and said, "Yeah okay, I'm naked in that scene." Trier added that it also enhanced realism because it occurs during a breakup sequence - "I try to make films about honest situations, and sometimes you are naked in those situations."

The final installment in Trier's Oslo trilogy.

Anders Danielsen Lie told director Joachim Trier before filming started, "I want to do the best acting I've ever done." Trier revealed, "He's gotten better with his craft, and he's gotten even braver about exposing deeper emotions." Danielsen Lie worked closely with costar Renate Reinsve to tell his character's story through her eyes, as she's the lead character. He added, "There's an old-fashioned masculinity to [my character]. He feels that he belonged to a time that has passed and he is alienated by the fragmentation of culture in the digital world." Danielsen Lie ended up receiving the best reviews of his career after the film premiered at the Cannes film festival.

At the beginning of the movie, Julie leaves Surgery because, she says, it's too similar to carpentry. In real life, Renate Reinsve is a carpenter.

Peter Bradshaw of The Guardian described the film as "one of Cannes' best" and "an instant classic".
