Paul Czinner (30 May 1890 – 22 June 1972) was a writer, film director, and producer.
Czinner was born in Budapest, Austria-Hungary. After studying literature and philosophy at the University of Vienna, he worked as a journalist. From 1919 onward, he dedicated himself to work for the film industry as writer, director and producer. In 1924, he offered the leading role in his film Nju to Elisabeth Bergner. They became partners, and after the persecution of the Jewish people by Adolf Hitler they fled to Vienna and then London, where they were married. Despite Czinner's homosexuality, the union proved a happy and personally and professionally enriching one for both partners. 1934 saw the realisation of his film Katharina die Grosse, with his wife playing the main role, although the film was not shown in Germany. They emigrated to the United States in 1940, working on Broadway.
