The Daughter of the Railroad Crossing Guard (1975)

Based on the idea by Roland Topor (screenwriter of Roman Polanski's The Tenant), this very curious completely silent melodrama tells the story of Mona, who has left her father, the railway gatekeeper, after being raped on the train track. She is kidnapped and taken to a Parisian whorehouse. However, a disinherited prince, Dudu who tries to rescue her, is himself kidnapped and forced to serve as a male prostitute. The two captives meet there and fall in love. They are taken away by different rich people - he to an Arab "harem," she to a surgeon's home.

Unfortunately the movie The Daughter of the Railroad Crossing Guard is not yet available on HBO Max.
