Alien/Aliens

The first two films from the hugely popular ‘Alien’ franchise. In ‘Alien’ (1979), when Kane (John Hurt) and the crew of the spaceship ‘Nostromo’ investigate a transmission from a deserted planet, he is attacked by an unknown organism which attaches itself to his face. The crew cut the creature off, but not before it has made Kane the host of a monstrous alien killer, one which will hatch out through his stomach and proceed to hunt down the crew one by one.
In ‘Aliens’ (1986), officer Ripley (Sigourney Weaver), the sole survivor of the alien attack on the ‘Nostromo’, awakes after 57 years in suspended animation when she is picked up by a salvage ship. She is put to work by the Company, but is horrified to discover that the planet where her ship picked up the original alien has now been colonised. When contact with the colony is lost, the Company sends Ripley on an investigative mission with a team of hardened Space Marines.
