The evil robot seductress from Metropolis, a 1927 German expressionist science-fiction film by Fritz Lang. Metropolis is set in a futuristic urban dystopia, and follows the attempts of activists Freder and Maria (Brigitte Helm) to overcome the class divide separating the wealthy intellectuals and working class. In this bizarre labor-relations parable, Rotwang the scientist creates a robotic double of Maria to generate chaos and discredit her.
Note: Maria is basically the great-grandmother of C-3PO.
