"Alien"

Alien is a 1979 science fiction horror film directed by Ridley Scott and written by Dan O'Bannon. Based on a story by O'Bannon and Ronald Shusett, it follows the crew of the commercial space tug Nostromo, who encounter the eponymous Alien, a deadly and aggressive extraterrestrial set loose on the ship. The film stars Tom Skerritt, Sigourney Weaver, Veronica Cartwright, Harry Dean Stanton, John Hurt, Ian Holm, and Yaphet Kotto. It was produced by Gordon Carroll, David Giler, and Walter Hill through their company Brandywine Productions, and was distributed by 20th Century Fox. Giler and Hill revised and made additions to the script; Shusett was executive producer. The Alien and its accompanying artifacts were designed by the Swiss artist H. R. Giger, while concept artists Ron Cobb and Chris Foss designed the more human settings.

Alien premiered May 25, 1979, as the opening night of the fourth Seattle International Film Festival, presented in 70mm at midnight before receiving a wide release on June 22, and was released September 6 in the United Kingdom. It was met with critical acclaim and box-office success, winning the Academy Award for Best Visual Effects, three Saturn Awards (Best Science Fiction Film, Best Direction for Scott, and Best Supporting Actress for Cartwright), and a Hugo Award for Best Dramatic Presentation, along with numerous other nominations. It has been consistently praised in the years since its release, and is considered one of the greatest films of all time. In 2002, Alien was deemed "culturally, historically, or aesthetically significant" by the Library of Congress and was selected for preservation in the United States National Film Registry. In 2008, it was ranked by the American Film Institute as the seventh-best film in the science-fiction genre, and as the 33rd-greatest film of all time by Empire.

The success of Alien spawned a media franchise of films, novels, comic books, video games, and toys. It also launched Weaver's acting career, providing her with her first lead role. The story of her character's encounters with the Alien creatures became the thematic and narrative core of the sequels Aliens (1986), Alien 3 (1992), and Alien Resurrection (1997). A crossover with the Predator franchise produced the Alien vs. Predator films, which includes Alien vs. Predator (2004) and Aliens vs. Predator: Requiem (2007). A prequel series includes Prometheus (2012) and Alien: Covenant (2017), both directed by Scott.

The commercial space tug Nostromo is on a return trip back to Earth with a seven-member crew in stasis: Captain Dallas, Executive Officer Kane, Warrant Officer Ripley, Navigator Lambert, Science Officer Ash, and two engineers, Parker and Brett. Detecting a transmission, the ship's computer, Mother, awakens the crew. Company policy requires any potential distress signal be investigated, so they land on the moon, sustaining damage from its atmosphere and rocky landscape. Parker and Brett repair the ship while Dallas, Kane, and Lambert head out to investigate. They discover the signal comes from a derelict alien ship and enter it, losing communication with the Nostromo. Ripley deciphers part of the transmission, determining it to be a warning, but cannot relay this information to those on the derelict ship.

Meanwhile, Kane discovers a chamber containing hundreds of large, egg-like objects. When he touches one, a creature springs out, breaks through his helmet, and attaches itself to his face. Dallas and Lambert carry the unconscious Kane back to the Nostromo. As acting senior officer, Ripley refuses to let them aboard, citing quarantine regulations, but Ash overrides her decision and lets them inside. Ash attempts to remove the creature from Kane's face, but stops when he discovers that its blood is an extremely corrosive acid. It later detaches on its own and is found dead. The ship is partly repaired, and the crew lifts off. Kane awakens with some memory loss, but is otherwise unharmed. During a final crew meal before returning to stasis, he chokes and convulses. A small alien creature bursts from Kane's chest, killing him, and escapes into the ship.

The crew attempts to locate it with tracking devices and capture or kill it with nets, electric prods, and flamethrowers. Brett follows the crew's cat Jones into a landing leg compartment, where the now-fully-grown alien attacks Brett and disappears with his body. After a heated discussion, the crew decide the creature must be in the air ducts. Dallas enters the ducts, intending to force the alien into an airlock, but it ambushes and kills him. Lambert implores the others to abandon ship and escape in its small shuttle, but Ripley, now in command, explains it will not support four people and says they will continue the plan of flushing out the alien.

Now with access to Mother, Ripley discovers Ash has been secretly ordered by the company to bring the alien back, with the crew deemed expendable. She confronts Ash, who tries to choke her to death. Parker intervenes and clubs Ash, knocking his head loose and revealing him to be an android. Ash's head is reactivated, and they learn he was assigned to ensure the creature's survival. He expresses admiration for the creature's psychology, unhindered by conscience or morality, and taunts them about their chances of survival. Ripley cuts off his power; as they leave, Parker incinerates him.

The remaining crew decides to self-destruct the Nostromo and escape in the shuttle. Parker and Lambert are killed by the creature as they gather supplies. Ripley initiates the self-destruct sequence, but finds the alien blocking her path to the shuttle. She retreats and attempts unsuccessfully to abort the self-destruct. With no further options, she makes her way to the shuttle and barely escapes as the Nostromo explodes.

As Ripley prepares for stasis, she discovers that the alien is aboard, having wedged itself into a narrow space. She puts on a spacesuit and uses gas to flush the creature out. It approaches Ripley, but before it can attack, she opens an airlock door, almost blowing the creature into space. It manages to hang on by gripping the frame. Ripley shoots it with a grappling hook, but the gun catches as the airlock door closes, tethering the alien to the shuttle. It pulls itself into an engine exhaust but Ripley fires the engines, blasting the creature away into the depths of space. After recording the final log entry, she places Jones the cat and herself into stasis for the trip home to Earth.
