Predator the greenlight, Aliens writer/director James Cameron had been working on a story for a fifth Alien film. Alien director Ridley Scott had talked with Cameron, stating "I think it would be a lot of fun, but the most important thing is to get the story right." In a 2002 interview, Scott's concept for a story was "to go back to where the alien creatures were first found and explain how they were created"; this project eventually became Scott's film Prometheus (2012). On learning that Fox intended to pursue Alien vs. Predator, Cameron believed the film would "kill the validity of the franchise" and ceased work on his story, "To me, that was Frankenstein Meets Werewolf.

Screenwriter Peter Briggs created the original spec screenplay in 1990–1991, which was based on the first comic series. In 1991, he successfully pitched the concept to 20th Century Fox, who owned the film franchises, although the company did not move forward with the project until 2002; a video game produced by Capcom as a tie-in to the unmade film saw independent release in 1994. The project was delayed chiefly because the studio was working on Alien Resurrection. A draft penned by James DeMonaco and Kevin Fox described as "pretty
