Alien

The crew of the space cargo ship Nostromo, which lands on a moribund planet in response to a faint SOS. Inside a crashed ship, the crew members come upon strange pods, one of which spews forth a repellently fleshy insectile creature that locks on to the face of the unlucky Kane. Despite Ripley's advice, science officer Ash allows Kane to return to the ship, where the creature finally releases its grip. Soon one of its offspring explodes horribly from Kane's stomach and scurries away. Dallas, the vessel's captain, leads the others in a search for the rapidly growing, acid-dripping alien before it can cut them down--one by one.
