Sigourney Weaver is one of our favorite science fiction action heroes, so we were really sad when she came out and said "science fiction didn't exist as a movie genre" before the 1950s. She added: "The Cold War made us edgy [and] so did arrogant science fooling around with the unknown and unnatural." Sorry, Sigourney, scifi movies have been around for as long as there have been moving pictures. We've compiled a list of some of the most amazing pre-1950s scifi movies to help you catch up.
