Making a sequel to Ridley Scott's 1979 classic "Alien" should have been a disaster. This was a movie that defined a whole new sub-genre of outer-space horror, a perfectly structured scarefest that also introduced one of cinema's greatest-ever monsters to the world.
Luckily, James Cameron — then one of Hollywood's hottest properties off the back of "The Terminator" — has never been a shrinking violet, and was brave enough to face the Xenomorph challenge head-on. Reinventing the franchise as a muscular sci-fi action movie, he created a whole new sub-genre of his own with a film every bit as memorable as its predecessor.
