Alien

Alien is one of science fiction’s most influential franchises, built around the Xenomorph, a perfect biological weapon whose only purpose is propagation through the systematic destruction of whatever host species it encounters. Created by Ridley Scott and H.R. Giger and launched in 1979, the franchise spans nine films, a television series, multiple games, and decades of comics and novels. After years of uneven entries, Alien: Romulus in 2024 and the FX series Alien: Earth in 2025 returned the franchise to its horror roots and commercial strength simultaneously.

Alien (1979) and the Xenomorph

Ridley Scott directed the original Alien from Dan O’Bannon’s screenplay, released in May 1979. The film follows the commercial crew of the Nostromo, a deep space mining vessel, diverted to investigate a distress signal on an alien moon. Ellen Ripley, played by Sigourney Weaver, is the warrant officer who survives the encounter with a creature that uses human bodies as incubators and kills everything it cannot use as a host. The Xenomorph’s design came from Swiss artist H.R. Giger, whose biomechanical aesthetic gave the creature an unsettling quality that no practical effects could fully explain. The result is one of the most effective monster designs in cinema history, and the film’s horror owes as much to Giger’s visual language as to O’Bannon’s claustrophobic screenplay.

The Xenomorph lifecycle, facehugger to chestburster to adult drone, was established across the first two films and has remained the biological foundation of every subsequent entry. The creature’s acid blood, its second mouth, and its total indifference to anything but reproduction gave it a logic that horror audiences found genuinely disturbing rather than simply frightening.

Aliens (1986) and the Franchise Template

James Cameron wrote and directed Aliens in 1986, returning Ripley to the Xenomorph-overrun colony on LV-426 with a squad of Colonial Marines. The sequel shifted the register from horror to action while expanding the mythology with the introduction of the Alien Queen, the hive structure, and Ripley’s surrogate maternal relationship with the survivor Newt. Aliens is widely considered one of the strongest sequels in film history and defined what the franchise’s action-oriented entries have tried to replicate ever since. Michael Biehn, Paul Reiser, Lance Henriksen, and Bill Paxton completed a cast that gave the film a texture the subsequent entries consistently failed to match.

Alien 3, Resurrection, and the Middle Era

David Fincher directed Alien 3 in 1992 in a notoriously difficult production that he has since disowned, killing Newt and Hicks in the opening minutes and confining Ripley to a prison planet. Alien Resurrection in 1997, directed by Jean-Pierre Jeunet from a Joss Whedon screenplay, cloned Ripley two hundred years after her death and pushed the franchise into increasingly surreal territory. Both films have their defenders but neither captured the commercial or critical response of the first two entries, and Resurrection’s ending left the franchise with nowhere obvious to go.

Prometheus, Covenant, and the Prequel Era

Ridley Scott returned to the franchise with Prometheus in 2012, a thematic prequel exploring the Engineers, the alien species whose ship Ripley’s crew investigated in 1979, and the origins of the Xenomorph. The film divided the fanbase sharply, praised for its visual ambition and criticized for its narrative choices. Alien: Covenant in 2017 moved closer to direct prequel territory, connecting the android David to the creation of the Xenomorph and setting the stage for events that would eventually lead to the Nostromo’s discovery. Neither film fully satisfied audiences looking for a return to the first film’s horror approach.

Alien: Romulus (2024)

Fede Alvarez directed Alien: Romulus for 20th Century Studios, released theatrically in August 2024. The film is set between the events of Alien and Aliens and follows a group of young colonists who board an abandoned space station only to encounter the Xenomorphs. Cailee Spaeny stars as Rain Carradine alongside David Jonsson as her android companion Andy. Romulus grossed over $350 million worldwide against an $80 million budget, the strongest commercial performance for an Alien film in decades, and its return to the original film’s contained horror approach was broadly praised after the prequel era’s mixed reception.

Alien: Earth (FX Series)

Alien: Earth debuted on FX in August 2025, broadcasting internationally on Disney+, and was renewed for a second season in November 2025. Created by Noah Hawley, the series is the first Alien story set on Earth and takes place in 2120 when the planet is governed by five corporations including Weyland-Yutani. The series introduced new Xenomorph designs, altered the established lifecycle lore, and expanded the franchise’s mythology in ways that Romulus deliberately avoided. The combination of a successful theatrical film and a well-reviewed streaming series running simultaneously gave the franchise a cultural presence it had not maintained in decades.

Alien Games and Alien: Isolation

The franchise has produced games across multiple decades, with Alien: Isolation in 2014 widely considered the definitive Alien game and one of the finest horror games ever made. Developed by Creative Assembly and published by Sega, Isolation cast the player as Amanda Ripley, Ellen’s daughter, investigating her mother’s disappearance on a space station stalked by a single, unkillable Xenomorph. The game’s AI-driven alien behavior made it genuinely terrifying in a way that matched the original film’s register rather than the action orientation of most licensed games. A sequel to Alien: Isolation has since been confirmed in development.

The Future of the Alien Franchise

The Romulus sequel is in active development. Fede Alvarez departed as director in September 2025 after finishing the script with Ridley Scott, with Michael Sarnoski reported to be on the shortlist to direct as of March 2026. Alien: Earth continues in production for its second season. The franchise enters the back half of the 2020s with more active productions across film, television, and games than at any point in its history.
