20 Most Iconic Monster Introductions In Movie History

5. The Alien - Alien

Before John Carpenter introduced us to his vision of a very twisted Thing, another groundbreaking science fiction horror movie had already scared the living daylights out of audiences. Ridley Scott's Alien has gone down in history as one of the most frightening science fiction movies of all time, and for good reason. Credit for the shocking effect of the creature in Alien deserves to go to designer H. R. Giger as much as it does to Ridley Scott - it's far and away one of the most iconic monsters ever put up on the big screen. Few readers will be unfamiliar with the first time it literally rears its ugly head, bursting from John Hurt's chest and terrifying the rest of the crew of the Nostrodomus. https://www.youtube.com/watch?v=LsD6AL3HJtM
