THE DAY THE EARTH STOOD STILL

'''THE DAY THE EARTH STOOD STILL. Robert Wise, dir.''' USA: 20th Century Fox, 1951.

Possibly the classic SF film featuring a robot. Based on H. Bates's "Farewell to the Master" (q.v. under Fiction) but without the story's final revelation that the robot is the master and the "man" the creature. See for duality of robot as both servant and threat. Discussed by Sobchack in The Limits of Infinity.
