"Now it can hit you too!"
Alien 2: On Earth tagline

Alien 2: On Earth (Alien 2: Sulla Terra), also known as Alien Terror and Strangers, is a 1980 science fiction film written and directed by Ciro Ippolito. Co-produced by the United States of America and Italy, it is a low-budget, unofficial and unauthorized sequel to the 1979 film Alien, although the plot has little to no connection to the original film. It follows a group of friends as they go caving together, only to come into contact with a voracious alien creature that gestates inside a living human host, unwittingly brought to Earth by a doomed human spacecraft.

As an unauthorized sequel, 20th Century Studios had nothing whatsoever to do with the film's production and it is not considered a part of the official franchise. In fact, Fox attempted to sue director Ippolito $10,000,000 for using "Alien" in the film's title, but a British lawsuit pointed out that there was already a novel from the 1930s called Alien, and thus the case was dismissed. The concept of making unofficial sequels to mainstream theatrical productions was somewhat common in Italy during the 1970s and 1980s. Perhaps the most notable example of this trend is Zombi 2 (known variously as Zombie or Zombie Flesh Eaters internationally), an unofficial sequel to George A. Romero's Dawn of the Dead that went on to find its own success and create a franchise of films.


As the world awaits the return of a crew of astronauts on a deep space mission, a young woman named Thelma Joyce appears on a television talk show to discuss caves. Soon after her interview begins, Thelma has a horrible psychic vision. After the spacecraft returns to Earth with its occupants missing, a girl on a beach discovers a weird, blue, pulsating rock. Soon after the discovery, her mother finds the girl dead, having her face ripped off.

Some time later, Thelma and her husband Roy meet up with their friends at a bowling alley. After a short gambling session, they leave to go cave climbing in a cave complex nearby. On the way to the caves, the group stops at a roadside café to buy food and change into their caving gear. Thelma's friend Burt discovers a blue rock. The group can't figure out what type of rock it is, and Burt gives the rock to Thelma. The group finally arrives at the cave, and quickly rappel to the bottom to set up camp for the night. As the group turns in for the night, Thelma tells Roy that she feels that something horrible is about to happen, but Roy calms her down.

The following day, the group splits up to take pictures of the many rock formations. While exploring, Jill notices the blue rock appears to be pulsating. As she picks it up, the rock opens up and a creature attacks her face. Thelma, who was with Jill, witnesses the attack and panics. After Roy again calms her down, the group elects to go and search for Jill.

The group rappels down into the hole and finds Jill, alive and apparently unharmed but unconscious. She is hoisted back up out of the hole and set aside by herself, still unconscious. While the rest of the group prepares to climb back up, a creature erupts from Jill's left eyeball and attacks Bill, dragging him upside down before beheading him with its tail.

The infant alien quickly grows into a mature shape-shifting creature and begins slaughtering the group of friends one by one, multiplying in number with each kill. Only Thelma and Roy manage to outrun the aliens and escape the caves. They jump into their car and speed towards the city to find help. Along the way, they discover a police car, but no police officers are in sight. They stop at the roadside café again, but there is nobody there. Roy tries to call for help on a payphone, but no operator is available. They get back into the car and continue towards the city.

Thelma and Roy finally arrive, but find the city is likewise deserted. They head to the bowling alley, and split up. Roy is suddenly killed by an alien waiting in the back. The creature chases Thelma through the bowling alley, until she manages to bludgeon it and make her escape. Outside, Thelma runs through the empty city streets, calling for help but getting no answer. She finally stops yelling and sits down at an intersection, despondent, as text on screen warns the audience, "Now it can hit you too!"

Release and Reception

Alien 2: On Earth was released theatrically in Italy on April 11, 1980 and in West Germany on March 19, 1982. The English-dubbed version of the film was never released theatrically in the United States. Instead, it was released directly-to-video under the title Alien Terror. The US version of the film is slightly different, being much darker overall and having the sky at the end of the film tinted red, for unknown reasons.

Reviews were generally favorable regarding the film's splatter scenes, special effects, soundtrack, location and the tension, but the cinematography, pacing, story and characters drew mixed to negative responses from critics. Currently, the film holds a 4/10 on IMDb. Adam Tyner of DVD talk wrote, "James Cameron once summed up his follow-up to Alien as 'forty miles of bad road'. Alien 2, meanwhile, is eighty-four miles of bad, period."

The recent Blu-ray release of the film, however, has received more positive reviews, with particular praise being given to the restoration of the film by Midnight Legacy. Tom Landy of High-Def Digest.com gave the film 3 stars out of 5 and wrote, "It's tough to outright recommend this one to the masses, but for fans of the film or collectors of oddball cult curiosities then this Blu-ray is the definitive disc of Alien 2: on Earth to own."

Alternate titles

Alien 2: On Earth has had a somewhat confusing release history. As is fairly common with Italian movies from the period, the original title has been altered, twisted, or sometimes completely changed multiple times since the film's release, often making it hard to find.

Alien 2 Midnight Legacy Blu-Ray cover

On March 22, 2011, Midnight Legacy re-released the English-dubbed version of the film on DVD and Blu-ray in the United States under its original title, Alien 2: On Earth. The re-release includes fully remastered picture and audio. This version of the film was believed to be longer than any other version, however an Italian television broadcast of the film contains footage not included in this release. This release includes a special effects outtake reel and a theatrical trailer for the film. Another Blu-ray was released by 88 Films in the UK in 2016. This release uses the same remaster and special features as the Midnight Legacy release, and also contains an additional featurette in which Eli Roth discusses the film.


  • The plot in the film Alien takes place in the year 2122 AD. Alien 2: On Earth, however, appears to take place somewhere in the 1980s, even though its story is supposedly set after the events on the Nostromo.
    • Additionally, the astronauts and space capsule glimpsed at the beginning of the film bear no resemblance to the Nostromo or its occupants. They are depicted through the use of archival footage of a real space shuttle's return to earth.
  • The Alien in the film differs considerably from the creature seen in the original Alien (and the rest of the official franchise). While it shares the key trait of gestating inside a human host, each stage of its life cycle is otherwise quite different:
    • The Eggs in the film barely resemble the Eggs from Alien. In the original film, the Eggs were grey-green, leathery and opened on top. The Eggs in Alien 2 resemble rocks, are blue and pulsate. They still open at the top, however.
    • The Alien's infant form bursts out of the victim's face rather than their chest (leading some fans to christen it the "Faceburster").
    • Finally, the creature's adult form is shown to be a shape-shifting creature that attempts to assimilate other lifeforms. In this last regard it is similar to the Thing creature from the franchise of the same name.
  • Some critics have suggested that the film's narrative details and visual design and effects appeared to have been a major influence on the 2005 film The Descent.
  • The conquest of Earth by the Alien, hinted at at the end of the film, is a major plot point in the early comic books and novels of the Alien franchise.
  • Since Alien 2 is an "unauthorized" sequel, it has never been released in any Alien film collection or boxed set with the other films in the series (nor is it ever likely to be).
  • A sequel to this film, with the working title Alien 3, to be directed by Bruno Mattei, was conceived but never realized.[citation needed]
