''Ex Machina'' (stylized as ''ex_machina'') is a 2015 British science fiction thriller film written and directed by Alex Garland. It stars Domhnall Gleeson, Alicia Vikander, Sonoya Mizuno and Oscar Isaac. ''Ex Machina'' tells the story of a programmer who is invited by his employer to administer the Turing test to an android with artificial intelligence. Made on a budget of $15 million, the film grossed over $36 million worldwide and received positive reviews. == Plot == Caleb is a programmer for Bluebook, the world's most popular search engine. He wins a one-week visit to the secluded home of Bluebook CEO Nathan. The only other person there is Kyoko, a mute housemaid. Nathan has built a humanoid robot named Ava with artificial intelligence (AI). To program her behaviour, he harvested personal information from billions of Bluebook users, using their search queries as indicators of human thought, and hacked billions of cell phones for recordings of human expressions and body language. He wants Caleb to administer the Turing test to Ava, a test designed to measure an AI's ability to persuade the tester it is human. Caleb points out that this is not a fair test, as he already knows Ava is an AI; Nathan responds that Caleb must judge whether he can relate to Ava despite knowing she is artificial. Ava has a robotic body and a synthetic brain, but a human-looking face, and is confined to her apartment. Caleb grows close to her, and she tells him she wants to be with him. She reveals that she can trigger power outages that temporarily shut down the surveillance system that Nathan uses to monitor the complex and their conversations. During one outage, she tells Caleb that Nathan is a liar who cannot be trusted. Caleb encourages Nathan to drink until he passes out, then steals his security card to access the mainframe system. He alters some of Nathan's code, then watches footage of earlier androids Nathan built; they damage themselves in their desperation to escape. He also discovers that Kyoko is an android. Back in his room, Caleb cuts his arm open and investigates his flesh. At their next meeting, Ava cuts the power; Caleb says he fears that Nathan will reprogram her, "killing" her personality. They agree on a plan: Caleb will get Nathan drunk and reprogram the system to open all the complex's doors at the next outage, and Caleb and Ava will escape together. The next day, Nathan reveals that he recorded Caleb and Ava's conversation using a battery-powered camera. He explains his real motive for inviting Caleb: to see if Ava was convincingly human enough to seduce Caleb into helping her escape. Caleb reveals that he has already reprogrammed the doors to open while Nathan was drunk the previous night. When Ava cuts the power, she leaves her confinement and Nathan knocks Caleb unconscious. As Nathan begins to drag Ava back to her confinement, Kyoko stabs him with a kitchen knife. Nathan knocks her inert, but Ava stabs him to death. She takes parts from prototype androids, giving her the appearance of a complete human, and leaves Caleb trapped inside a sealed room. She boards the helicopter meant for Caleb's departure and enters human society. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ex Machina (film)」の詳細全文を読む スポンサード リンク
