1920’s film culture is characterized by transnational and border-crossing endeavours. This paper explores the Danish production company Palladium and its close relation to the German producer and distributor Lothar Stark. Stark was a pioneer of the early German film industry, employed at PAGU before setting up his own firm Lothar Stark-Film GmbH in Berlin. Which role did Stark play in the Danish company’s entry into the German film market, with a series of films starring the comedic duo Pat and Patachon? Tracing their collaborative efforts in both Danish and German press coverage, this paper investigates the entangled history of Palladium and Lothar Stark. From the widespread success and popularity of Pat and Patachon in German cinemas to the protracted – and very public – legal feud in Austria concerning the ownership of the names “Pat and Patachon”. Thus, it is both a case study of the possibilities and limits of transnational film culture.
