World UFO Day: 11 alien movies that are out of this world

It’s World UFO Day! And for movie lovers, that means only one thing – it’s time to have a close encounter of the film kind. 

We’ve compiled a list of 11 of our favorite movies about little green men, space invaders, body snatchers, benevolent Kryptonians, and carnivorous plants. Some are very scary. Some are action-packed. One is a Disney movie! But they’re all guaranteed to entertain… or at least to make you look up at the sky.

And we’ll also tell you where you can stream each flick. Here’s a hint: A few of them can be streamed for free on Tubi. 

One final note, just so the truth is out there: We’ve omitted some of the most obvious choices, such as "Alien," "The Thing," "Aliens," "The Day the Earth Stood Still," "Alien vs. Predator,"  "District 9," "Super 8," the "Cloverfield" franchise, and all three – yes, three – Steven Spielberg masterpieces about extraterrestrials. A list of the very best alien movies would undoubtedly include all these and more, but we wanted to give you a chance to explore some uncharted territory. You know, just like an alien might explore Earth.
