Films like Avatar (2009) and Star Wars: The Force Awakens (2015) prove that science fiction is a popular subject when it comes to box office grosses. But are they on the same level as the greatest sci-fi movies of all time?

It's hardly a surprise that when Stanley Kubrick turned his hand to science fiction he came up with one of the greatest sci-fi movies of them all!

Alien (1979)

The 1986 sequel, Aliens, could also be considered the greatest. In Alien, the crew of the Nostromo welcome a rather unpleasant guest in the shape of a xenomorph.
