The document discusses the German Expressionist film movement of the 1920s. It reflects the isolation Germany experienced during WWI through abstract psychological landscapes and distorted scenes representing characters' states of mind. Many German filmmakers then emigrated to Hollywood and subtly adapted these techniques into 'B' films, influencing the new era of 'Film Noir' through shadows and lighting. Film Noir crime dramas were stylish Hollywood films from the 1940s-1950s influenced by German Expressionism's visual style using shadows and low key lighting to highlight situations and emotions.
