Alien is a 1979 science-fiction horror film directed by Ridley Scott, and starring Tom Skerritt, Sigourney Weaver, Veronica Cartwright, Harry Dean Stanton, John Hurt, Ian Holm and Yaphet Kotto. The film's title refers to a highly aggressive extraterrestrial creature that stalks and kills the crew of a spaceship. Alien received both critical acclaim and box office success, receiving an Academy Award for Best Visual Effects, Saturn Awards for 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 award nominations. It has remained highly praised in subsequent decades, being inducted into the National Film Registry of the Library of Congress in 2002 for historical preservation as a film which is "culturally, historically, or aesthetically significant". In 2008, it was ranked as the seventh-best film in the science fiction genre by the American Film Institute, and as the 33rd greatest movie of all time by Empire magazine. In an unspecified year in the future, the commercial spacecraft Nostromo is on a return trip to Earth with a 7-member crew in stasis. Detecting a mysterious transmission, possibly a distress signal, from a nearby planetoid, the ship's computer, the MU-TH-UR, awakens the crew. Under prior orders from their employers, the Nostromo lands on the planetoid and Captain Dallas, Executive Officer Kane, and Navigator Lambert head out to investigate and discover the signal is coming from a derelict alien spacecraft. Inside, they find the remains of a large alien creature whose ribcage appears to have exploded from the inside.
