The Day The Earth Stood Still 1951

The Day the Earth Stood Still (working titles: Farewell to the Master and Journey to the World) is a 1951 American science fiction horror film from 20th Century Fox, produced by Julian Blaustein and directed by Robert Wise. It stars Michael Rennie, Patricia Neal, Hugh Marlowe, Sam Jaffe, Billy Gray, Frances Bavier and Lock Martin. The screenplay was written by Edmund H. North, based on the 1940 science fiction short story "Farewell to the Master" by Harry Bates. The film score was composed by Bernard Herrmann.
Set in the Cold War during the early stages of the nuclear arms race, the storyline involves a humanoid alien visitor who comes to Earth, accompanied by a powerful robot, to deliver an important message that will affect the entire human race.
In 1995, the film was selected for preservation in the United States National Film Registry as "culturally, historically, or aesthetically significant". The 2008 remake The Day the Earth Stood Still stars Keanu Reeves and Jennifer Connelly.
When a flying saucer lands in Washington, D.C., the United States Army quickly surrounds it. A humanoid emerges and announces that he comes "in peace and with good will". When he unexpectedly opens a small device, he is shot and wounded by a nervous soldier. A tall robot emerges from the saucer and quickly disintegrates the Army's weapons. The alien orders the robot, Gort, to desist. He explains that the now-broken device was a gift for the President of the United States that would have enabled him "to study life on the other planets".
The alien, Klaatu, is taken to Walter Reed Army Hospital. After surgery, he uses a salve to quickly heal his wound. The Army is unable to enter the saucer. Gort stands outside, silent and unmoving.
Klaatu tells the President's secretary, Mr. Harley, that he has a message that must be delivered to all the world's leaders simultaneously. Harley tells him that in the current world situation, this is impossible. Klaatu proposes that he spend time among ordinary humans to better understand their "unreasoning suspicions and attitudes". Harley rejects the proposal, and Klaatu remains locked in his hospital room.
Klaatu escapes and stays in a boarding house using the name Mr. Carpenter, adopted from a dry cleaner's suit tag. Among the residents are young widow Helen Benson and her son Bobby. Helen's suitor, Tom Stevens, becomes jealous of the stranger.
Bobby takes Klaatu on a tour of the city, including a visit to his father's grave in Arlington National Cemetery; Klaatu learns that most of the dead are soldiers killed in wars. They also visit the Lincoln Memorial. When Klaatu asks Bobby, "Who is the greatest living person?", Bobby suggests Professor Barnhardt. They visit the scientist's home, but he is out; Klaatu sees that Barnhardt's blackboard is covered with equations (an attempt to solve the three-body problem). Klaatu adds to them and, after being discovered by the housekeeper, leaves his contact information.
