Just stumbled over the following snippets from ↑Info on German Expressionist Films:
German expressionist films were prevalent in the 1920s. Amongst the most well remembered are films such as The Cabinet of Dr Caligari (Robert Weiner, 1920), Nosferatu (F.W. Murnau, 1922), Metropolis (Fritz Lang, 1927) and Sunrise (F.W. Murnau, 1927). These films were united by highly stylized visuals, strange asymmetrical camera angles, atmospheric lighting and harsh contrasts between dark and light. Shadows and silhouettes were an important feature of expressionism, to the extent that they were actually painted on to the sets in The Cabinet of Dr Caligari. [...]
The story lines of German expressionist films matched the visuals in terms of darkness and disillusionment. Often sombre in mood and featuring characters from a corrupt underworld of crime, the films’ dramatic effects produced motifs of claustrophobia and paranoia. The same words could be used to describe 1940s Hollywood film noir, a genre hugely influenced by German expressionism. Film noir is typified by Bogart and Bacall in films such as The Big Sleep. Fritz Lang himself also went on to make notable film noirs such as Fury and You Only Live Once. [...]
Metropolis is a stylistically avant garde science fiction film. It features an archetypal mad scientist character who creates a robot doppleganger of the film’s heroine Maria. The evil robot defies her master, ultimately leading to the destruction of the city. Director Fritz Lang is the Godfather of psychologically well rounded characters, providing believable, multi-faceted (anti) heroes, prophetic in many ways of Humphrey Bogart’s screen persona.
Another fine detail of the interwovenness of cyberpunk and film noir: The cyberpunk movie ‘Metropolis’ influences film noir, which in turn influences cyberpunk.
