Filmmakers from Berlin and Vienna exiled in Hollywood

Poster for the film Casablanca, directed by Michael Curtiz, starring Ingrid Bergman, Paul Henreid, Conrad Veidt and Peter Lorre, 1942.

The symbiosis of European and American cultures enabled Hollywood to produce the greatest masterpieces of cinema, as filmmakers from Berlin and Vienna, during the 1930s in particular, brought their know-how and culture, which they adapted to their new environment. German expressionism, psychoanalysis and Viennese humour contributed to film noir, light and serious comedy, melodrama and the Western.
