One of the funniest movies of the 1990s, the first Men in Black was a frightening, intriguing variation on vampire-chasing, ghost-busting comedies, starring Tommy Lee Jones as Agent K, a senior operative of a top-secret government agency that monitors the activities of extraterrestrial aliens. "At any one time there are 1,500 aliens on Earth," he tells his new sidekick, Agent J (Will Smith), adding, "Most of them are here in Manhattan." Seeing it was about as refreshing and surprising as attending the opening of the first ever McDonald's.
