"Aliens have long fascinated us. Humanity has wondered about life on the moon and among the stars at least as early as the second century, when Lucian wrote about his travels to the moon and stars and his encounters with the people there. And those imaginings made it onto film as early as 1918 with Holder-Madsen's A Trip to Mars.
The Fermi Paradox might have scientists scrambling for answers on why we haven't been able to make contact with alien races, but filmmakers have rescued us from the Great Silence with countless fictional encounters with aliens throughout cinema history. Whether visitations from malicious invaders or those coming to save us from ourselves, stories of humanity encountering alien races on their own turf or movies taking place a long time ago in a galaxy far, far away, these 50 films present us with a wide-range of life on other planets."
