1920s

1920
The Cabinet of Dr. Caligari (German: Das Cabinet des Dr. Caligari) is a 1920 German silent horror film, directed by Robert Wiene and written by Hans Janowitz and Carl Mayer. Considered the quintessential work of German Expressionist cinema, it tells the story of an insane hypnotist (Werner Krauss) who uses a somnambulist (Conrad Veidt) to commit murders. The film features a dark and twisted visual style, with sharp-pointed forms, oblique and curving lines, structures and landscapes that lean and twist in unusual angles, and shadows and streaks of light painted directly onto the sets.

The script was inspired by various experiences from the lives of Janowitz and Mayer, both pacifists who were left distrustful of authority after their experiences with the military during World War I. The film makes use of a frame story, with a prologue and epilogue which, in a twist ending, reveals the main narrative is actually the delusion of a madman. Janowitz has claimed this device was forced upon the writers against their will. The film's design was handled by Hermann Warm, Walter Reimann (de) and Walter Röhrig (de), who recommended a fantastic, graphic style over a naturalistic one.

The film thematizes brutal and irrational authority; Dr. Caligari represents the German war government, and Cesare is symbolic of the common man conditioned, like soldiers, to kill. In his influential book From Caligari to Hitler, Siegfried Kracauer says the film reflects a subconscious need in German society for a tyrant, and is an example of Germany's obedience to authority and unwillingness to rebel against deranged authority. He says the film is a premonition of the rise of Adolf Hitler and the Nazi Party, and says the addition of the frame story turns an otherwise "revolutionary" film into a "conformistic" one. Other themes of the film include the destabilized contrast between insanity and sanity, the subjective perception of reality, and the duality of human nature.

The Cabinet of Dr. Caligari was released just as foreign film industries were easing restrictions on the import of German films following World War I, so it was screened internationally. Accounts differ as to its financial and critical success upon release, but modern film critics and historians have largely praised it as a revolutionary film. Critic Roger Ebert called it arguably "the first true horror film", and film reviewer Danny Peary called it cinema's first cult film and a precursor for arthouse films. Considered a classic, it helped draw worldwide attention to the artistic merit of German cinema and had a major influence on American films, particularly in the genres of horror and film noir.

1922
Nosferatu, eine Symphonie des Grauens (translated as Nosferatu: A Symphony of Horror; or simply Nosferatu) is a 1922 German Expressionist horror film, directed by F. W. Murnau, starring Max Schreck as the vampire Count Orlok.

The film, shot in 1921 and released in 1922, was an unauthorized adaptation of Bram Stoker's Dracula, with names and other details changed because the studio could not obtain the rights to the novel (for instance, "vampire" became "Nosferatu" and "Count Dracula" became "Count Orlok"). Stoker's heirs sued over the adaptation, and a court ruling ordered that all copies of the film be destroyed. However, one print of Nosferatu survived, and the film came to be regarded as an influential masterpiece of cinema. As of 2015, it is Rotten Tomatoes' second best-reviewed horror film of all time.

1927
Metropolis is a 1927 German expressionist epic science-fiction drama film directed by Fritz Lang. Lang and his wife Thea von Harbou wrote the silent film, which starred Brigitte Helm, Gustav Fröhlich, Alfred Abel and Rudolf Klein-Rogge. Erich Pommer produced it in the Babelsberg Studios for Universum Film A.G.. It is regarded[by whom?] as a pioneering work of the science-fiction genre in movies, being among the first feature length movies of the genre.

Made in Germany during the Weimar Period, Metropolis is set in a futuristic urban dystopia and follows the attempts of Freder, the wealthy son of the city's ruler, and Maria, a poor worker, to overcome the vast gulf separating the classes of their city. Filming took place in 1925 at a cost of approximately five million Reichsmarks, making it the most expensive film ever released up to that point. The motion picture's futuristic style shows the influence of the work of the Futurist Italian architect Antonio Sant'Elia.
The film met with a mixed response upon its initial release, with many critics praising its technical achievements and social metaphors while others derided its "simplistic and naïve" presentation. Because of its long running-time and the inclusion of footage which censors found questionable, Metropolis was cut substantially after its German premiere: large portions of the film went missing over the subsequent decades.

Numerous attempts have been made to restore the film since the 1970s-1980s. Music producer Giorgio Moroder released a version with a soundtrack by rock artists such as Freddie Mercury, Loverboy and Adam Ant in 1984. A new reconstruction of Metropolis was shown at the Berlin Film Festival in 2001, and the film was inscribed on UNESCO's Memory of the World Register in the same year, the first film thus distinguished. In 2008 a damaged print of Lang's original cut of the film was found in a museum in Argentina. After a long restoration process, the film was 95% restored and shown on large screens in Berlin and Frankfurt simultaneously on 12 February 2010.
