This 2005 Til Schweiger film is a romantic comedy surrounding a stereotypical bachelor and an escaped mental patient. He shows her the world outside of the mental hospital, including how to take the bus or get money from an ATM.
Alongside Til Schweiger is Johanna Wokalek. She’s been in other hits such as Nordwanderung and Der Baader Meinhof Komplex and the Verfilmung Emilia Galotti. Heinrich Keller is played by Michael Mendl, who we may recognize best from Dark.
There is a few flashes of nudity 4 minutes in. 37 minutes in there is a short scene with a man who thinks the woman is a prostitute, during which sexual comments and remarks are made. An hour and 11 minutes in, there is the beginnings of an aggressive sexual scene (with the woman as the aggressor), which is preceded by Nick looking for Leila and being pulled into a room. I feel as if there was one more scene with nudity once Leila was in his apartment, but I may have blinked too long this viewing or completely misremembering the scene that is at the beginning of the movie.
