Metropolis

Metropolis (1927)
director Fritz Lang
writer Thea von Harbou
starring Brigitte Helm

In Fritz Lang’s scifi epic Metropolis, Bridget Helm stars as the saintly Maria who urges the ruling class to respect the lowly workers that keep the city functioning. As her popularity grows, the Master of Metropolis commands a scientist to create a robot changeling who will trick the workers into abandoning their goals of equality. The machine is given the face and body of Maria, but its soul is her evil twin. Instead of frustrating the working class the robot sews a revolution and corrupts the city’s wealthiest sons who fight for her attention. She dances as the Whore of Babylon while Metropolis collapses in ruin.
