List Rules Vote up your favorite science fiction films that were released in the 1970s

Star Wars is probably the most well known 1970s science fiction movie, but don't count out the other strong contenders on this best '70s sci-fi movies list. This is the decade that also gave us the original Alien, A Clockwork Orange, and Westworld. Vote up the greatest 1970s sci-fi movies, and feel free to add any films we may have missed!

This list of 1970s science-fiction films reveals that the decade featured a trend of smart movies tackling social issues. Soylent Green and Logan's Run both depict overbearing governments that take population control to appalling extremes. Then you have A Clockwork Orange (a film that's still shocking even by today's standards), which is the ultimate movie about the extremes a government will go to to control its unruly citizens. Should these films get a higher ranking as the top '70s sci-fi movies for their audacity to take on important issues with such brazen material?

Of course, not all the '70s sci-fi movies are classics. In fact, for every Star Wars, there are multiple cheesy '70s sci-fi films. Reading up on the genre, you'll quickly notice that there aren't many '70s science fiction movies that are simply good - they're either great or terrible.  What will end up as number one on this list of the top 1970s science fiction films? The outcome is in your hands!
