This weekend sees the release of the epically restored Fritz Lang film Metropolis. Originally screened in 1927, this dystopic science fiction fantasy tells a story of an exploited proletariat forced into rebellion after being targeted by their masters in a violent act of oppression. Read what you will into that but take note of the incredible special effects that went on to define everything we know and love about sci-fi. It is a genius film, prophetic and compelling and full of what do you call it…? Robot-impressionism.
