Movie: Alien (1979)

Hands down, the most memorable scene in Ridley Scott's seminal sci-fi/horror classic Alien is also one of cinema's all-time greatest shock moments: Nostromo executive officer Kane (John Hurt), having recently been face-hugged by a small crab-like alien, suddenly begins convulsing at the spaceship's dinner table, before his chest bursts open and a tiny E.T. slithers across the floor.

What Alien's chestbuster rapidly becomes is the film's scariest attribute. Known as the Xenomorph, the tall, lanky bastard—armed with a little fang-filled mouth inside its bigger mouth—is a truly awe-inspiring creation, one that comes from the mind of Swiss artist H.R. Giger and has yet to be matched in its nightmarish beauty. —MB
