Want to know what state-of-the-art computers, both the home and military versions, looked like 30 years ago? This 1983 drama shows you precisely that, as Matthew Broderick – also 30 years younger – plays a high-school computer nerd who accidentally hacks into a super-restricted American military computer. A simple question, from the computer, leads to a very complex situation. The special effects, almost a third of a century later, are almost laughable. The message, however, is anything but.
