Sigourney Weaver kicks mean alien butt in her star-making role as Ripley in this sci-fi classic.

Weaver, Tom Skerritt, Ian Holm, Yaphet Kotto and Harry Dean Stanton are among the crew of the commercial spaceship Nostromo, who are stricken with terror after an unstoppable alien monster is taken on board and bursts spectacularly out of John Hurt’s stomach.

Director Ridley Scott’s ground-breaking 1979 movie was one of the most influential films of its era, with its blend of science fiction and horror blowing through the end of the decade like a breath of fresh air.

The iconic monster (created by the Swiss surrealist artist HR Giger) is still terrifying nearly 40 years later and the meticulously designed sets create a potent feeling of claustrophobia.

Showing in tribute to Stanton, who died last month.
