Alien (franchise)

Alien is a science-fiction horror film franchise centered on a film series that depicts Warrant Officer Ellen Ripley (Sigourney Weaver) and her battles with an extraterrestrial lifeform, commonly referred to as "the Alien".

Produced by 20th Century Fox, the series began with Alien (1979), directed by Ridley Scott. It was followed by three sequels, released in 1986, 1992 and 1997. A planned prequel series directed by Scott is in development, beginning with the 2012 release of Prometheus.

The series has led to numerous books, comics and video game spin-offs. Related to the franchise is the two-part Alien vs. Predator series, which combines the continuities of Aliens with the Predators from the Predator film series.

Background

After completion of the film Dark Star (1974), writer Dan O'Bannon thought to develop some of the ideas (especially the theme of "alien hunts crew through a spaceship") and create a science-fiction horror film. Provisionally called Memory, screenwriter Ronald Shusett collaborated with O'Bannon on the project, adding elements from a previous O'Bannon script, Gremlins, which featured gremlins causing mayhem aboard a World War II bomber and wreaking havoc with the crew. The duo finished the script, initially entitled Star Beast, which was later changed to Alien after O'Bannon noticed the number of times the word "alien" occurred in the script. Their script was sold to Brandywine Productions, a company formed by producers Gordon Carroll, David Giler, and Walter Hill that had a distribution deal with 20th Century Fox. The writers imagined a low-budget film, but the success of Star Wars inclined 20th Century Fox to invest millions on the production.
