The 1983 film WarGames is a teen film, but it showed us what can happen when you combine the widespread availability of computer technology with the dangers of the Cold War. A young hacker finds his way into the US military's system for simulating, detecting, and executing nuclear attacks. What could possibly go wrong? WarGames was the first time I had ever seen Matthew Broderick, and I thought "This kid is going places." He was 21 at the time, but looked much younger.
Later we heard a story about the production. The filmmakers couldn't get any access to the Pentagon's facilities, so they used their imaginations to build the set that housed the program. Later, military officials said that the state-of-the-art computers portrayed in the movie were just a dream to them, as the real thing was quite obsolete.
