German Expressionism originated in Germany in the early 20th century as a unique style of filmmaking. It is characterized by strong contrasts, shadows, asymmetric angles, and high contrast lighting. These techniques create an unsettling and disorienting atmosphere on screen. German Expressionist films often dealt with themes of social decay, corruption, and paranoia. The style had a major influence on Hollywood and American film noir after many German filmmakers fled the rise of Nazism in the 1930s.
