Close Encounters of the Third Kind is an Earth based science fiction which was released in 1977 and is directed by Steven Spielberg.
Coming out in the same year as Star Wars, it didn't get as much exposure as it might have done if it was shown in a different year. When things such as ships turning up in deserts and U.F.O.s being reported by air traffic control, things take a turn for the good or worse. alien space ships are spotted by Roy Neary one night as he goes to investigate a power cut.
Roy begins a sort of downward spiral from then on, including building a mountain out of mash potato then mud. He manages to identify the mountain and with his wife goes off to investigate. The mountain is the Devils Tower National Monument near Sundance, Wyoming. The military has put an exclusion zone right round the area saying there's poisonous gas killing person and they need to evacuate. Unperturbed, the Nearys venture closer to the mountain and discover it is where the Military are planning on communicating with the alien ships. The aliens communicate in a series of beeps and lights. You only get a brief look of what the aliens look like but it is sufficient to discover they look like the typical alien, long thin legs, a big head and white or grey.
