Step-by-step explanation:
The 1927 movie you are referring to is Metropolis. This silent science-fiction drama, directed by Fritz Lang, is a pioneering work in the genre and is set in a dystopian future where class divisions are stark. The plot centers around Rotwang, the mad scientist character who creates a humanoid robot with the intention of bringing back his deceased love, but ultimately ends up using the android in a plot to control the city and challenge the ruling industrialists. The iconic image of the robot, known as the Maschinenmensch (Machine-person), is a lasting symbol of the film's exploration of technology, power, and humanity.
