In the mid-1940s and the 1950s, scores of people began to report seeing mysterious flying discs in the sky. It could have been mass hysteria caused by the trauma of going through one massive war and the fear of another, but Hollywood was happy to capitalize on the paranoia. Aliens ships descended on the cinema and have continued blowing up Washington, D.C. to this day. Here are the 12 best UFOs that have ever invaded movie screens.


12) E.T. the Extra-Terrestrial

Forget for a minute that the fat spaceship in E.T. looks like an Aquapod water bottle. When E.T.'s mother ship landed, it was the culmination of a string of fantastic events experienced by a bunch of American suburbanites. It was a scene that managed to be majestic, happy and tear-jerkingly sad. As adults, we know E.T. had to go back to his own kind, who we glimpsed waiting for him in the ship. But as kids, we didn't want E.T. to go home! Combined with the soaring John Williams score, the arrival and departure of this UFO still gives us lumps in our throats. Maybe it's indigestion from eating all those Reese's Pieces.

11) Fire in the Sky

The UFO that whisks away logger Travis Walton isn't too impressive on the outside; it's more of a vague shape with a red glow. What is truly frightening is what Walton encounters on the inside - partially weightless catacombs and the mutilated bodies of abducted humans who didn't survive the aliens' experiments. Having Travis save himself by climbing up a "rope" that turns out to be a dead person's intestines is pure genius. Travis then gets caught by the realistic aliens and subjected to a series of horrifying tests, topped off by having a needle inserted into his eye. What's creepier is that the movie is based on a supposedly true story. However, the whole sequence in the ship was Hollywood-ized, as Walton's version was a lot more dopey and benign.

10) Contact

This was a UFO of a different sort -- it was built by humans, based on blueprints sent by aliens as an invitation to the stars. Jodie Foster's character makes the voyage in the ship, which is a pod dropped between massive, spinning rings that are pulsating with electromagnetic energy. Foster is hurled across the cosmos through wormholes, catching a glimpse of a beautiful alien civilization and encountering a being who appears as Foster's character's father to tell her that humans have just taken the first step of an amazing journey. To everyone else on Earth, it appears that Foster's ship just dropped into the ocean below it and that she hallucinated the whole thing. However, her recording devices on the pod show she was gone for 18 hours. This film, based on a book by Carl Sagan, gave a hint of the wonders that could really be out there.

9) *batteries not included

The twist in this film was that the little flying saucers who came to save residents of a New York City apartment building from evil land developers and fix things were actually robot aliens. The good-natured UFOs even replicated, having baby flying saucers. It was all very cute. It was the mid-1980s and Steven Spielberg was involved; what did you expect?

8) The Day the Earth Stood Still

It's been said that if aliens really wanted to make contact with humans, they should stop buzzing farmers and just land on the White House lawn. In this 1951 film, that's pretty much what happens. The humanoid Klaatu and his powerful robot Gort arrive on a mission of peace. However, humans quickly screw everything up with their violent ways, ignorance and paranoia. Klaatu tells everyone that the rest of the universe fears the Earth's development of atomic power and will use an army of Gorts to destroy the planet if they persist in their destructive ways. Good going, humanity. Despite a likely accurate portrayal of how badly humans would cock up a peaceful alien visit, viewers are treated to an archetypical vision of an introductory alien visit when Gort and Klaatu's classic disc-ship descends and lands in Washington, D.C. It's both amazing and tense.

7) Star Trek IV: The Voyage Home

A massive cylindrical probe shows up over Earth and begins monkeying with the planet's weather, brining Earth to its knees. The mysterious alien cylinder is so huge that not even the Enterprise could take it down, although that wasn't an issue since Kirk blew his own ship out of the sky in the previous movie. The alien probe wants to talk to whales, by God, and Kirk and crew travel back in time to steal two of the now extinct mammals. Once everyone gets back to the future, the probe talks to the whales about goodness knows what and then heads back to parts unknown. What was cool about the probe was that it managed to be very alien in a franchise where new aliens were met during every movie and episode.
