Alien is a 1979 science fiction horror film directed by Ridley Scott and starring Sigourney Weaver.
The film's title refers to its primary antagonist: a highly aggressive extraterrestrial creature which threatens and kills the crew of a spaceship.
The crew of the deep space mining ship Nostromo are awaken from hypersleep to investigate a strange signal from a nearby planet. While investigating the signal, they discover it was intended as a warning, and not an SOS.
Alien gained both critical acclaim and box office success.
It has remained highly praised in subsequent decades.
When 'Alien' was released in 1979, it caused almost as much talk as 'Star Wars' did when released two years earlier. The science fiction genre was being revolutionized at this time and 'Alien' had a horror characteristic to it which was psychological, visually striking and compelling with the type of strength in silence not seen since '2001: A Space Odyssey' in 1968.
The success of Alien spawned a media franchise of novels, comic books, video games, and toys, as well as three sequel and two prequel films.
It also launched Weaver's acting career by providing her with her first lead role, and the story of her character Ripley's encounters with the Alien creatures became the thematic thread that ran through the sequels Aliens (1986), Alien 3 (1992), and Alien Resurrection (1997).
The subsequent prequels Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007) abandoned this theme in favor of a crossover with the Predator franchise.
