James Cameron may well be the king of the sequel considering both this film and Terminator 2: Judgement Day are two of the best follow-ups of all time (Piranha II: The Spawning maybe not so much). In this action-packed continuation of Alien, a group of space marines and the sole survivor of the previous film (Weaver) try to destroy a nest of vicious creatures that have decimated a human colony on a distant moon.
