Film scholars are celebrating the discovery of lost reels of the 1925 German SF classic “Metropolis” which had strong fascist overtones, which few today publicly recognize. How fascist? Well, look at the co-screenwriter.
First, is the link on the discovery of the lost footage
[And here Harbou's bio]:
Thea Gabriele von Harbou (December 27, 1888 – July 1, 1954) was a German actress and author of Prussian aristocratic origin. She wrote her first film script together with Fritz Lang. Fritz Lang became her second husband in 1922, and they collaborated in the following years, writing the screenplays for Metropolis and M together. They separated in October 1931 and divorced in 1933.
In 1932, a year before Adolf Hitler came to power, she joined the National Socialist German Workers Party, which presumably led to the divorce from Lang, who left Germany in 1934 for Paris after his film The Testament of Dr. Mabuse had been banned by the Nazi government.
Harbou wrote the script for Der Herrscher (1937), directed by Veit Harlan and starring Emil Jannings. The movie celebrates unconditional submission under absolute authority, eventually finding reward in total victory.
After the war she was detained by the British.
