#3: Alien
Ridley Scott’s Alien brought deep-space horror to life with a crew facing a perfect organism aboard their ship. Sigourney Weaver’s tough-as-nails Ripley becomes the ultimate survivor in a claustrophobic nightmare filled with acid blood and face-huggers.
It blended sci-fi wonder with genuine terror, creating one of the most iconic creatures ever while showing that the scariest things often come from the darkness just beyond the lights.
