Aliens, 40 years on: the film that made the Xenomorphs legendary

What is Aliens and why does it remain so important?

When Alien arrived in cinemas in 1979, it introduced one of the most recognisable monsters in film history. Seven years later, James Cameron returned to that universe with a sequel that expanded the scale of the conflict and changed the balance between horror, science fiction and action.

Aliens brings back Ellen Ripley, played by Sigourney Weaver, decades after the events of the first film. This time she does not face a single creature in the narrow corridors of a spacecraft, but a colony of xenomorphs alongside a unit of Colonial Marines.

The film established elements that would become emblems of the franchise: the Alien Queen, the Colonial Marines, motion trackers and the final confrontation led by Ripley. Its ability to expand the universe without simply repeating the previous formula explains much of its enduring cultural presence.

Few cinematic creatures have achieved the level of recognition enjoyed by the xenomorph. Originally designed by H. R. Giger for Alien, its combination of biomechanical forms and organic features created an image very different from the classic tradition of film monsters.

Aliens expanded that universe by showing a colony, a hierarchy and an Alien Queen. The threat ceased to be exclusively individual and became an organised species, capable of dominating an entire space and forcing the protagonists to rethink every decision.

The result extended beyond the screen. The franchise expanded into comics, video games, novels and collectibles, while its creatures, vehicles, weapons and settings became part of the imagery of contemporary science fiction.

The “40 Years of Aliens” exhibition at MADHORROR

MADHORROR, IFEMA MADRID’s international festival of horror, dark fantasy and Halloween culture, will hold its first edition from 30 October to 2 November 2026. Among its major exhibitions is “40 Years of Aliens”, created to commemorate the anniversary of James Cameron’s film.

Official information states that the exhibition will bring together a selection of original objects from the cinematic universes of the saga driven by Ridley Scott and James Cameron, courtesy of 20th Century Studios. The project forms part of the area dedicated to xenomorphs within MADHORROR’s exhibition programme.

The documentation of items associated with the space includes original objects and replicas from different films in the franchise. These include elements related to Alien, Aliens, Alien 3, Alien: Resurrection and Prometheus. The final selection on display should be confirmed through the event’s official information.

Items from the Alien universe planned for the project

The working inventory for the space includes pieces spanning several stages of the saga and allowing visitors to appreciate both the evolution of the creature and the breadth of its visual universe. The list distinguishes between original production objects and collectible replicas.

• Life-size bust of an Alien Warrior from Aliens, produced by Sideshow.
• Head of the Newt doll and a Reebok promotional poster signed by Carrie Henn.
• Hudson’s vest made by Terry English, the armourer who produced the originals for the film.
• 1:4 scale Ripley statue and replicas of Ripley’s boots signed by Sigourney Weaver.
• Models and replicas related to the motion tracker, pulse rifle and Power Loader P-5000.
• Original objects linked to Alien, including a section of the Nostromo staircase, production photographs, a revised script and a MU/TH/UR 6000 panel.

The specific presence of each item should be confirmed with the final installation and official programme, as the project inventory distinguishes between the core selection and items associated with premium fees.

Michael Biehn and the direct connection to Aliens

MADHORROR has also confirmed the participation of Michael Biehn, the actor who played Corporal Dwayne Hicks in Aliens. His presence connects the exhibition with one of the central characters in the group of Colonial Marines accompanying Ripley on the mission.

Biehn’s participation strengthens the anniversary tribute from two perspectives: the preservation of objects and the memory of those who worked in front of the camera. Specific details of his activities should be checked in the official MADHORROR programme.
