The Greatest Sci-Fi Movies of All Time

List Criteria: Science fiction films

What are the greatest sci-fi movies of all time? Science fiction films are among the most popular movies in cinematic history, with films like 'Star Wars' and 'Aliens' keeping audiences on the edge of their collective seats for decades. This list includes these classics, and many more, but it is by no means complete. Feel free to add your favorite sci-fi movies if they aren't listed, and vote for your favorites.

Great sci-fi films include stories of extraterrestrial life, time travel, space travel, robots and more. Some of these amazing science fiction movies are more fantasy-oriented, while others are a bit closer to reality. Either way, scifi films keep audiences rapt with tales of science and technology, combined, at times with the supernatural.

Some sci-fi films are based on classic novels or short stories by such heavyweight authors as H.G. Wells ('War of the Worlds,' 'The Invisible Man') or Philip K. Dick ('Blade Runner,' 'Minority Report').
