What is "querelle"

Querelle is a 1982 West German-French English-language drama film directed by Rainer Werner Fassbinder and starring Brad Davis, adapted from French author Jean Genet's 1947 novel Querelle de Brest. It marked Fassbinder's final film as a writer/director; it was posthumously released just months after the director died of a drug overdose in June 1982.
