The Cold War brought about a lot of technological advances, and WarGames explores what might have happened if artificial intelligence was one of them. The War Operation Plan Response (WOPR) supercomputer is accessed by a young hacker, triggering the computer’s simulation of nuclear war. A race then ensues to stop the computer before it actually starts World War III.
Less terrifying than the previous movies on this list, Her focuses more on the effect an artificial intelligence could have on human emotions. Joaquin Phoenix plays Theodore Twombly, a man who falls in love with an artificial-intelligence-powered operating system named Samantha, and the film explores the sorts of issues this relationship might have.
