Pressed for time, so I’m pointing you to a sublime blog called Strange Flowers, who has a write up of an absolutely amazing film, Algol: Tragödie der Macht (or is it Nacht? That’s what the title cards say) which is Algol: Tragedy of Power (or Night). UPDATE: James confirms that other references to the film use Macht, so the title card is likely wrong. More fitting for the theme anyway.
Wow, just wow: an SF German silent that pre-dates Metropolis by seven years and features the amazing decadent Sebastian Droste. Do yourself a favour and read the whole write-up, then watch the film. I’m still making my way through; I cheated and watched the last reel so I could see Droste dance. I think you can make your way through it fairly well even if your German isn’t that good; that’s the beauty of silent films. Watch out for the eye of the devil!
