WarGames (1983)
This was an old favorite for many younger baby-boomers, who were teenagers and in their twenties at the dawn of the personal computer age. This one was a bit more than amusing, though. It opened many eyes to both the potential and the dangers we faced while coming into the computer age. The government had these marvelous machines and the internet by which they communicated for decades before the public was given access from these ancient Commodore 64's, Amigas, and Atari home computers via phone line, back in the late 1970's. While this work is entertaining, it also bears a valid warning, even today. Broderick and Ally Sheedy both were 21, playing 17 year olds, competently.
