Alien (1979) On its way back to Earth, the commercial towing vehicle
Nostromo is diverted to a desolate
planetoid by a cryptic signal from a derelict alien spacecraft. Inside the alien ship, the crew discovers thousands of egg-like objects. A creature, released from one of the eggs, attaches itself to a crewman's face, rendering him unconscious. The others break quarantine to return him to the
Nostromo. The parasite dies and the crewman wakes up, seemingly unaffected. Soon afterwards, an alien organism bursts from his chest and grows rapidly into a large lethal creature, which the surviving crew attempt to kill. The
Nostromo is destroyed in an unsuccessful attempt to kill the creature, leaving
Ellen Ripley as the only survivor in the ship's lifeboat.
Aliens (1986) After 57 years in
hypersleep, Ripley awakens aboard a medical space station orbiting Earth. She recounts the events of the
Nostromo but is disbelieved by her superiors in the Weyland Yutani corporation, which has now begun to
terraform and colonise LV-426, the planetoid from the first film. When contact with the colony is lost, Ripley is persuaded to accompany a squad of marines to investigate. They discover the colonists have been wiped out after being directed by the company to secure the derelict ship reported by Ripley. There is only one survivor, a girl named
Newt. The aliens vastly outnumber and quickly overwhelm the marines, who fight for survival. Only a handful, including Ripley and Newt, escape.
Alien 3 (1992) Immediately following the events of
Aliens, the military ship USS
Sulaco, carrying the survivors, catches fire. The occupants are ejected in an escape pod, which crash-lands on the refinery/prison planet Fiorina "Fury" 161. All on board except Ripley are killed. An alien facehugger is also aboard, and impregnates an animal with an alien, which soon begins killing inmates and wardens. Ripley discovers an alien queen is growing inside her, and is determined to kill both herself and the creature before Weyland Yutani can exploit them.
Alien Resurrection (1997) Two hundred years after the events of
Alien 3, several clones of Ripley, including the Alien queen she was carrying, are grown by the military aboard the USM
Auriga. The military intends to exploit the Aliens, and uses humans kidnapped and delivered to them by a group of mercenaries as hosts for the queen's eggs. The Aliens escape, and Ripley 8 (a clone mixed with Alien DNA) and the mercenaries attempt to escape and destroy the
Auriga before it reaches Earth.
Prometheus (2012) In 2084, some 30 years before the events of
Alien, scientists Elizabeth Shaw and Charlie Holloway discover a star map among the remnants of several ancient Earth cultures. Accompanied by David 8 and hoping to discover the
origins of humanity, they journey aboard the spaceship USCSS
Prometheus and arrive in 2093 on the distant planet LV-223 in the
Zeta2 Reticuli system, the same region of space in which the
planetoid LV-426 from
Alien is found. There they discover the ancient remains of an advanced civilization, called the Engineers (apparently the same race as the dead pilot from the derelict ship in
Alien), who were developing biological weapons in the form of a pathogenic mutagen which could have driven the human race extinct. The horrors they encounter result in the loss of the crew except for David and Shaw.
Alien: Covenant (2017) Eleven years after the events of
Prometheus, the colony ship USCSS
Covenant, carrying thousands of colonists and hundreds of human embryos in
cryo-stasis, makes its way towards the planet Origae-6. The crew is awakened by a
neutrino blast and intercepts a transmission sent from Shaw, which they decide to trace to an apparently habitable Engineer home world (referred to as Planet 4), devoid of all non-floral life. When several crew members are infected by the same
mutagen encountered by the
Prometheus crew and give birth to a new breed of Alien, the Neomorphs, the android David 8 rescues them. It is revealed that he brought Shaw to the planet, where he killed all non-floral life and began experimenting on Shaw's corpse to engineer his own breeds of Aliens. His motive to replace human life with Aliens is made apparent, and with the birth of yet another new breed of Alien, a terraforming expert named Daniels and the remaining crew are forced to flee from the world. After disposing of the Aliens chasing them, the crew members return to the
Covenant and are put back into cryosleep by someone they believe to be their shipboard synthetic, Walter. Only when Daniels is put in her cryopod does she realize that Walter has been replaced by the identical David. With the crew, colonists, and embryos at his mercy, David contacts Weyland-Yutani back on Earth, stating that while the majority of the crew was killed in the neutrino blast, they would continue to Origae-6.
Alien: Romulus (2024) Five downtrodden young space colonists and a Synthetic encounter hostile Alien creatures while scavenging a derelict Weyland-Yutani space station in which they plan to scavenge Cryopods that enables them to survive a journey to another more liveable planet.
Crossover series Inspired by the
Dark Horse Comics series, the filmmakers of
Predator 2 (1990) incorporated an
Easter egg in which an Alien skull was seen in a Predator trophy case. Expansions upon this
shared universe between the
Alien and
Predator franchises followed through comics and video games, leading up to the launch of a film franchise with the release of
Alien vs. Predator in 2004, followed by
Aliens vs. Predator: Requiem in 2007. The franchise has spawned various comics, novels, video games, and other merchandise based upon or inspired by the films. A third film has been variously rumored since the production of
Requiem. In mid-2018,
Shane Black, the director of
The Predator, expressed his belief that a third
Alien vs. Predator could still happen, indicating the studio's interest in both franchises. In August 2024, Fede Álvarez, the director of
Alien: Romulus, also said he was open to directing a third
Alien vs. Predator film, proposing to Melanie Brooks and Anthony D'Alessandro of
Deadline Hollywood that he would enjoy directing it along with
Dan Trachtenberg, the director of the
Predator films
Prey (2022) and
Predator: Badlands (2025): "Maybe it's something I have to co-direct with my buddy Dan. Maybe we should do like Quentin Tarantino|[Quentin] Tarantino and
Robert Rodriguez did with From Dusk till Dawn|[
From]
Dusk till Dawn. I'll direct a half, and he'll direct another half." In October of the same year, Steve Abell (President of Fox Studios) stated that the studio has plans to eventually develop an
Alien and
Predator crossover film. The Weyland-Yutani Corporation featured in the
Alien franchise along with their particular android model featured in
Alien: Romulus appears in the upcoming
Predator: Badlands film as a stepping stone towards a third
Alien vs. Predator film.
Alien vs. Predator (2004) In 2004, a Predator mothership arrives in
Earth orbit to draw humans to an ancient Predator training ground on
Bouvetøya, an island about one thousand miles north of
Antarctica. A buried
pyramid giving off a "heat bloom" attracts a group of explorers led by billionaire and self-taught engineer Charles Bishop Weyland (
Lance Henriksen), the original founder and CEO of Weyland Industries, who unknowingly activates an Alien egg production line as a hibernating Alien queen is awakened within the pyramid. Three Predators descend to the planet and enter the structure, killing all humans in their way with the intention of hunting the newly formed Aliens, while the scattered explorers are captured alive by Aliens and implanted with embryos. Two Predators die in the ensuing battle with an Alien, while the third allies itself with the lone surviving human, Alexa "Lex" Woods (
Sanaa Lathan), while making their way out of the pyramid as it is destroyed by the Predator's wrist bomb and eventually does battle with the escaped Alien Queen on the surface. The Queen is defeated by being dragged down by a water tower into the dark depths of the frozen sea, but not before she fatally wounds the last Predator. The orbiting Predator mothership uncloaks and the crew retrieves the fallen Predator. A Predator elder gives Lex a spear as a sign of respect, and then departs. Once in orbit it is revealed that an Alien
Chestburster was present within the corpse, thus a Predalien hybrid is born.
Aliens vs. Predator: Requiem (2007) Set immediately after the events of the previous film, the
Predalien hybrid aboard the Predator scout ship, having just separated from the mothership shown in the previous film, has grown to full adult size and sets about killing the Predators aboard the ship, causing it to crash in the small town of
Gunnison, Colorado. The last surviving Predator activates a distress beacon containing a video recording of the Predalien, which is received by a
veteran Predator on the Predator homeworld, who sets off towards Earth to "clean up" the infestation. When it arrives, the Predator tracks the Aliens into a section of the sewer below the town. He removes evidence of their presence as he moves along using a corrosive blue liquid and uses a laser net to try to contain the creatures, but the Aliens still manage to escape into the town above. The Predator fashions a plasma pistol from its remaining plasma caster and hunts Aliens all across town, accidentally cutting the power to the town in the process. During a confrontation with human survivors, the Predator loses its plasma pistol. The Predator then fights the Predalien singlehandedly, and the two mortally wound one another just as the US air force drops a tactical nuclear bomb on the town, incinerating both combatants along with the Predalien's warriors and hive, as well as the few remaining humans in the town. The salvaged plasma pistol is then taken to Ms. Cullen Yutani of the Yutani Corporation, foreshadowing an advancement in technology leading to the future events of the
Alien films.
Future In the mid-1990s, screenwriter
Stuart Hazeldine wrote a
treatment,
Alien: Earthbound. Fox executives were impressed by the script, having read it after
Alien Resurrection had entered post-production. According to Sigourney Weaver, Joss Whedon had written an Earth-set script for
Alien 5, but Weaver was not interested and wanted it to be set on the original planetoid. She has remained open to a role on the condition that she likes the story. Before 20th Century Fox
greenlit Alien vs. Predator, James Cameron had been collaborating on the plot for a fifth
Alien film with another writer, but ceased work on learning of the crossover. Cameron stated that the crossover would "kill the validity of the franchise", and that "it was
Frankenstein Meets Werewolf" – like "
Universal just taking their assets and starting to play them off against each other." Although he liked the final product, he ruled out any future involvement with the series. In late 2008, Weaver hinted in an interview with MTV that she and Scott were working on an
Alien spin-off film, which would focus on the chronicles of Ellen Ripley rather than on the Aliens, but the continuation of Ripley's story has not materialized. In 2015, Sigourney Weaver expressed her interest in returning to the role of Ripley with
Neill Blomkamp's story (purportedly titled
Alien: Awakening) which would tie into the first two
Alien films by taking place after
Aliens and foregoing involvement with the other two sequels. This was canceled in favor of Scott's own untitled third prequel (also purportedly titled
Alien: Awakening). In February 2019, James Cameron stated that he was working on reviving Blomkamp's project. In June 2020, Brandywine Productions revealed that a screenplay for a new installment in the original series called
Alien V, centered around Ripley, had been written by Walter Hill and David Giler. In an interview with
The Hollywood Reporter published in September 2022, Hill confirmed that the proposed alternative sequel involving Weaver would not be moving forward. Blomkamp reused some of his proposed concepts for
Alien V in his short film
Rakka, also starring Sigourney Weaver. After the
acquisition of 21st Century Fox by The Walt Disney Company, it was officially confirmed at the 2019
CinemaCon that future
Alien films are in development. In May 2019,
Variety reported that the third prequel film was "in the script phase", with Ridley Scott attached to serve once again as director. In September 2020, Scott confirmed that work on the next installment is ongoing, but whether the plot would be connected to
Prometheus and
Alien: Covenant was undecided. In October 2024, Scott confirmed he was already developing a new
Alien film. In June 2025, Scott announced his departure from the
Alien franchise, saying "where it's going now, I think I've done enough, and I just hope it goes further", while expressing his critiques of the
Alien sequels; though in August, Scott updated his stance and was open to a third prequel film saying, "Another
Alien prequel — yeah, if I get an idea, for sure". In October 2025, Sigourney Weaver announced that she has had discussions with The Walt Disney Company and 20th Century Studios to reprise her role in an upcoming project, with a script being written by
Walter Hill. As of March 2026, following the success of
Alien: Romulus and the TV show
Alien: Earth, a
Romulus sequel was said to be in the works.
Romulus director Fede Álvarez is writing the screenplay and will co-produce with Ridley Scott. New directors for the sequel are being explored, including
Michael Sarnoski, who wrote and directed
Pig (2021),
A Quiet Place: Day One (2024), and
The Death of Robin Hood (2026)
