input question: Generate a question that has the following answer: Washington D.C. for the following movie plot: When a flying saucer lands in Washington, D.C., the Army quickly surrounds the spaceship. A humanoid (Michael Rennie) emerges, announcing that he has come in peace. As he advances, he unexpectedly opens a small device and is shot by a nervous soldier. A tall robot emerges from the saucer and quickly disintegrates the soldiers' weapons with an energy ray. The alien orders the robot, Gort, to stop. He explains that the broken device was a gift for the President, which would have enabled him "to study life on the other planets". The alien is taken to Walter Reed Hospital, where he reveals his name: Klaatu. After surgery, Klaatu uses a salve to quickly heal himself. Meanwhile, the military is unable to enter his saucer; Gort stands outside, silent and unmoving. Klaatu tells the President's secretary, Mr. Harley (Frank Conroy), that he has a message that must be delivered to all the world's leaders simultaneously. Harley tells him that such a meeting in the current political climate is impossible. Klaatu suggests that he be allowed to go among humans to better understand their "unreasoning suspicions and attitudes". Harley rejects the proposal and leaves Klaatu under guard. Klaatu escapes and lodges at a boarding house as "Mr. Carpenter", the name on the dry cleaner's tag on the suit he "borrowed".

While Helen and her boyfriend Tom Stephens (Hugh Marlowe) go out, Klaatu babysits Bobby. The boy 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 those buried there were killed in wars. The two visit the Lincoln Memorial, then the heavily guarded spaceship. Klaatu asks Bobby who is the greatest living person; Bobby suggests Professor Barnhardt (Sam Jaffe), who lives in the capital. Bobby takes Klaatu to Barnhardt's home, but the professor is absent....???

The cannibals then imprison Robert in a cave, where he is starved. Robert manages to escape with a native girl (Me Me Lai), who he keeps tied to a cord. The native girl tries to escape, and Robert rapes her. The two then find Rolf, whose leg is infected with gangrene. The three of them wander through the jungle until they eventually find the landing field. The cannibals then set upon them and kill the native girl, then cook and eat her. After Rolf is hit in the chest with a spear, Robert fights and kills one of the cannibals with a spear laced with cobra venom. Robert then eats the native's liver to frighten the other cannibals.
