15 Best Alien Movies On Netflix In UK [Updated 2022]


Who knows what kind of aliens would visit Earth? Maybe they’d be cute little blue-shaded monsters with glow-in-the-dark paws, but maybe they’d be giant, gelatinous monsters causing our swift destruction.

Given that the rare glimmers we see never turn out to be aliens, it’s definitely difficult to tell. However, the movies below portray many alternative situations, from the terrifying to the wholesome.

If you have a Netflix membership, we’d like to recommend some great Alien Movies on Netflix for a relaxing weekend.

When we say “best,” we’re referring to films that have the most exciting plots, the most surprising plot twists, and the most accurate depictions of human emotion following that of the aliens.
