Alien: Covenant is a 2017 science fiction horror film directed and produced by Ridley Scott, and written by John Logan and Dante Harper from a story by Michael Green and Jack Paglen. A joint American and British production, it is part of the Alien franchise, serving as a sequel to Prometheus (2012). It features returning star Michael Fassbender, with Katherine Waterston, Billy Crudup, Danny McBride, and Demián Bichir in supporting roles. It follows the crew of a colony ship that lands on an uncharted planet and makes a terrifying discovery.

In 2012, before the release of Prometheus, Scott discussed the prospects of a sequel and new trilogy, and this film was confirmed that August. Principal photography began on April 4, 2016, at Milford Sound in Fiordland National Park, New Zealand, and wrapped on July 19, 2016. Effects houses Odd Studios and CreatureNFX provided the film's makeup and animatronic creature effects. Scott said the film's first cut was 2 hours and 23 minutes, which was edited down by over twenty minutes.

Alien: Covenant premiered in London on May 4, 2017. It was released by 20th Century Fox on May 12 in the United Kingdom, and on May 19 in the United States. It received generally positive reviews from critics but was considered a box office disappointment, grossing $240 million against a production budget of $97–111 million.

In 2104, the spaceship Covenant is en route to colonize the planet Origae-6, carrying 2,000 colonists and 1,140 human embryos in cryogenic stasis. A sudden supernova burst damages the ship and kills several colonists, including the captain, Branson. Walter, an advanced android, awakens key personnel to address the situation. During repairs, the crew detects a human voice broadcast from an uncharted, habitable planet. Against the protests of Branson's wife Daniels, new captain Chris Oram decides to investigate.

The crew sends a lander to the planet's surface, where an expedition team tracks the broadcast to a crashed alien ship. Two crew members are unknowingly infected by airborne spores from the local fungi. Alien creatures known as neomorphs rapidly grow inside the pair, killing them in the process, and then attack the team, resulting in the lander's destruction. One neomorph is killed before the survivors are rescued by David, a predecessor of Walter's model that was discontinued for being too human-like.

David leads the survivors to a temple surrounded by thousands of dead humanoids. He claims that he and chief science officer Elizabeth Shaw—the sole survivors of the spaceship Prometheus, which vanished ten years earlier—arrived in the alien ship. However, they lost control and it crashed, leading to Elizabeth's death and releasing a deadly pathogen that annihilated the planet's fauna. The pathogen infects any living organism, either killing it or creating aggressive hybrids.

David reveals his disappointment with Walter's model for lacking his creativity and humanity, and derides their inventor, Peter Weyland, as unworthy of his creations. David confesses his love for Elizabeth, the only person who treated him kindly. When a neomorph infiltrates the temple and kills another team member, David attempts to communicate with it but becomes enraged when Oram kills it. Confronting David, Oram learns that the android has been experimenting with the pathogen to engineer new creatures. David tricks Oram into approaching a facehugger parasite, which fatally impregnates him with a xenomorph embryo.

As the team searches for missing members, Walter discovers Elizabeth's dissected corpse, used by David in his experiments. David admits to releasing the pathogen deliberately and expresses his disgust for humanity, which he believes is a dying species that his creations will replace. Walter challenges David, pointing out inaccuracies in his understanding of human history, suggesting David's conclusions are flawed. David seemingly disables Walter, unaware of his self-repair abilities.
