Interviewed at the 'BD Freeman Show', Sarah Nevada Grether revealed she and Emil von Schönfels didn't have to practice the sex scenes before filming them. "We just got closer and closer as friends. My co-star Emil is an amazing actor, a very young and very courageous actor, very crazy. Yeah, we became friends... I'm not his mother in real life, of course it helps a lot... We got to a level where we could connect and it didn't matter what the lines were. It didn't really matter that we were making intimate scenes because we had a lot of trust."
Asked about the explicit sex scenes, director Isabelle Stever said, "I wanted to shoot the sex scenes in such a way that they are not erotic, but sensual. The novel says they explore each other. The first scene in the bathroom is almost like an investigation. I wanted a visuality that would show them coming together and at the same time rolling off each other, a coming together in a poetic space. A mother asking her son to do homework while jerking him off has a strong irony. I wanted to show this scene in such a way that this irony is not in the foreground."
