Question: Generate a question about the following movie plot: In 1943, after their successful mission on the Greek island of Navarone, Major Keith Mallory (Robert Shaw) and Sergeant John Miller (Edward Fox) are sent to find and kill Nicolai. Originally thought to be a traitor who informed the Germans about Miller and Mallory during the Navarone mission, Nicolai is now known to be Colonel von Ingorslebon, a dedicated German spy believed to have infiltrated the Yugoslav Partisans as "Captain Lescovar" (Franco Nero). To get to Yugoslavia, the two men pair with "Force 10", an American sabotage unit, led by Colonel Mike Barnsby (Harrison Ford), which has its own mission there. To maximise security, Force 10 steals a Lancaster bomber from a British air base in Termoli, Italy, rather than requisitioning one; but they are spotted by Military Police MPs before they can take off. Weaver (Carl Weathers), a US Army sergeant under arrest by the MPs, joins with Force 10 and forces his way onto the plane. Barnsby and crew successfully "escape" Termoli, only to be shot down by Luftwaffe night fighters. Only Barnsby, Mallory, Miller, Weaver, and Force 10 member Doug Reynolds (Angus MacInnes) manage to escape the crippled plane. On the ground, the survivors run across a group they believe to be their allies, Communist Yugoslav Partisans, led by Captain Drazak (Richard Kiel). Force 10's rescuers are soon revealed to be collaborationist Chetniks (nationalist Serb guerrillas) under German control. The Germans take the team into custody but do not know their mission, so Mallory and Barnsby tell the commander, Major Schroeder (Michael Byrne), that they are criminals fleeing Allied authorities. To keep Schroeder from opening Miller's suitcase, which contains his special explosives, Mallory tells him that it contains a new wonder drug called "penicillin" which will spoil if exposed to air. By the next morning, the prisoners are told that Schroeder has opened the case, finding it full of firewood. Surprised, Mallory and Barnsby improvise an excuse, "admitting" they buried the samples. Schroeder...

Please help improve it by removing unnecessary details and making it more concise. (December 2009) (Learn how and when to remove this template message) On Planet 51, green humanoids with snail-like feelers and pointed ears live peacefully in a society reminiscent of the 1950s United States, but with alien technology and 1950s-themed alien homes. In the town of Glipforg, Lem is a teenager with a new part-time job at the local planetarium and a long-time crush on his neighbor, Neera. His best friend is Skiff, a big fan of the Humaniacs films. Lem tries to ask Neera on a date, but her hippie friend, Glar, keeps interrupting with his protest songs. A mysterious spacecraft goes into orbit around Planet 51 and sends out a signal. On Planet 51, under a secret Army installation called Base 9 (their version of Area 51), there is a basement filled with Earth artifacts including robotic satellites launched by the United States and the Soviet Union. The spacecraft's signal activates Rover, a wheeled A.I. probe. Rover escapes, following a program to locate the newly arrived astronaut. The Planetary Army becomes suspicious after Rover's escape and begins to investigate. The spacecraft touches down in Lem's backyard; NASA astronaut Charles "Chuck" T. Baker emerges. As Chuck plants the United States flag, he steps on a "rubber ducky" someone left on the ground. Everyone stares, and Chuck tries to get back into his module. Shocked when he realizes he is on an inhabited planet, Chuck runs about wildly and hides at the planetarium as the Army arrives on the scene. Planetary Army General Grawl consults Professor Kipple about the "alien invader". The Army quarantines the area and asks citizens to start a local civil defense force to prevent the citizens from becoming "zombies". At the planetarium, Lem discovers Chuck's hiding place. They are surprised to discover they speak the same language. Realizing this alien is no threat, Lem decides to help Chuck, hiding...
