Problem: Given the question: Generate a question about the following movie plot: Dr. Douglas Martin (Peter Graves) is a nuclear scientist working on atomic bomb tests. While collecting aerial data on a United States Air Force (USAF) atomic blast at Soledad Flats, he loses control of his aircraft and crashes. He appears to have survived, unhurt, walking back to the air base with no memory of what happened. On his chest is a strange scar that was not there before the crash. At the base hospital, Martin acts so strangely that the USAF brings in the FBI to investigate, thinking he might be an impostor. He is eventually cleared but told to take some time off. Martin protests being excluded from his project while on leave. When an atomic test is set off without his knowledge, Martin steals the data, then goes back to Soledad Flats and places the information under a stone. An FBI agent follows him, but Martin is able to elude him until he crashes his car. Now back at the hospital, he is given truth serum. Deep under the drug's influence, Martin tells a story about being held captive, by space aliens in their underground base., The aliens, with large, bulging eyes, are from the planet Astron Delta. They had revived his lifeless body as he had died in his aircraft. The aliens plan to exterminate humanity using giant insects and reptiles, grown with the radiation absorbed from our own atomic bomb tests. Martin intuits that the aliens use stolen electric grid power to control their powerful equipment. This so that the A-bomb's released energy levels can be predicted and then balanced. The aliens wiped his memory and hypnotized him into collecting the data for them. The FBI agent (Steve Pendleton) and the base commander (James Seay) are skeptical of this incredible story and keep him confined at the hospital. Nevertheless, the attending physician says that Martin genuinely believes that what he told them is true. With calculations made with a slide rule, Martin determines that if he shuts off the power to Soledad Flats for just 10 seconds, it will create an overload in the aliens' equipment. So he...

Problem: Given the question: Generate a question about the following movie plot: In Bridger's Wells, Nevada in 1885,[7] Art Croft (Harry Morgan) and Gil Carter (Henry Fonda) ride into town and enter Darby's Saloon. The atmosphere is subdued due to recent incidents of cattle-rustling. Art and Gil are suspected to be rustlers because they are rarely seen in town. A man enters the saloon and announces that a rancher named Larry Kinkaid has been murdered. The townspeople immediately form a posse to pursue the murderers, whom they believe are cattle rustlers. A judge tells the posse that it must bring the suspects back for trial, and that its formation by a deputy (the sheriff being out of town) is illegal. Art and Gil join the posse to avoid being its target. Davies (Harry Davenport), who was initially opposed to forming the posse, also joins, along with "Major" Tetley (Frank Conroy) and his son Gerald (William Eythe). Poncho informs the posse that three men and cattle bearing Kinkaid's brand have just entered Bridger's Pass. The posse encounters a stagecoach. When they try to stop it, the stagecoach guard assumes that it is a stickup, and shoots, wounding Art. In the coach are Rose Mapen (Mary Beth Hughes), Gil's ex-girlfriend, and her new husband, Swanson (George Meeker). Later that night in Ox-Bow Canyon, the posse finds three men sleeping, with what are presumed to be stolen cattle nearby. The posse interrogates them: a young, well-spoken man, Donald Martin (Dana Andrews); a Mexican, Juan Martinez (Anthony Quinn); and an old man, Alva Hardwicke (Francis Ford, brother of film director John Ford). Martin claims that he purchased the cattle from Kinkaid but received no bill of sale. No one believes Martin, and the posse decides to hang the three men at sunrise. Martin writes a letter to his wife and asks Davies, the only member of the posse that he trusts, to deliver it. Davies reads the letter, and, hoping to save Martin's life, shows it to the others. Davies believes that Martin is innocent and does not deserve to die. The Mexican "Juan", who is recognized as a gambler named Francisco...
