Men in Black (1997)

The film takes ufology's long-running Men in Black legend — shadowy officials said to visit witnesses and pressure them into silence — and flips it into a breezy sci-fi comedy. Here the MIB are not a menace but a covert bureau, hidden in New York, that registers and polices Earth's extraterrestrial "immigrants." With Agents K and J, their signature shades, and a memory-wiping neuralyzer, Sonnenfeld turns a Cold War-era conspiracy motif into mainstream blockbuster fun. Adapted from Lowell Cunningham's comic^[1], it carried the phrase "Men in Black" from fringe lore into everyday pop vocabulary.
