The Best Tagline in Cinema Was Conceived in the Most Unexpected Way

There are countless great taglines in film history, but the original Alien has arguably the single best one: "In space no one can hear you scream." It's frankly as iconic as the Xenomorph itself, and just as important in turning the movie into the cultural phenomenon it was when it came out by conveying everything people needed to know about it before going to the theater, without giving anything away. More than four decades later, it remains instantly recognizable and has gotten countless adaptations for other franchises, parodies, jokes, and more.
