Source of story
After a visit to an apparently uninhabited planet, the crew of the space tug Nostromo become aware that, inadvertently, they are sharing their ship with a terrifying life form.
The crew of the ship generally speak in a profane manner (like ship’s crews do). The presence and the attacks by the alien are extremely scary and involve blood and gore. No nudity but SW in her underwear once.
Surely everyone knows all about Alien. It is still a terrific film with lots of really shocking moments and virtually constant tension. It is worth a re-viewing.
