Director Felicitas Korn said it was very difficult to find the leading actors. "I cast for a year, looked at countless photos from the agencies on the Internet, looked at videotapes, but the right one wasn't among them. Then I asked Henriette Heinze, whom I already knew. She fit for Nadja and fortunately accepted. Golo Euler, who plays the male lead, was suggested to me by my caster, Stefany Pohlman," she said. In the event, it was a stroke of luck for the production that Heinze and Euler were cast to play the couple as the chemistry between the two is clearly there on the screen.
According to the producers, Felicitas Korn's approach to her story can be "compared with the directness in Intimacy by Patrice Chéreau, the immersion into the characters' emotional world in Trainspotting by Danny Boyle, and in its sensitivity with The Lover by Jean-Jacques Annaud. She directs her glance away from the documentary and pornographic to the aesthetic and emotional."
