much word-for-word like the Dark Horse comic book" was rejected by producer John Davis, who hoped to give the film an original approach by setting it on Earth. As there were six producers between the film franchises, Predator producer John Davis had difficulty securing the rights as the producers were worried about a film featuring the two creatures. Paul W. S. Anderson pitched Davis a story he worked on for eight years, adapting the Machiko Noguchi series, and showed him concept art created by Randy Bowen. Impressed with Anderson's idea, Davis thought the story was like Jaws in that it "just drew you in, it drew you in". Anderson started to work on the film after completing the script for Resident Evil: Apocalypse, with Shane Salerno co-writing.

To explain how these ancient civilisations "disappeared without a trace", Anderson came up with the idea that the Predators, if overwhelmed by the Aliens, would use their self-destruct weapons to kill everything in the area. H. P. Lovecraft's novella At the Mountains of Madness (1931) served as an inspiration for the film, and several elements of the Aliens vs. Predator comic series were included. Anderson's initial script called for five Predators to appear in the film, although the number was later reduced to three. As Alien vs. Predator was intended to be a sequel to the Predator films and prequel to the Alien series, Anderson was cautious of contradicting continuity in the franchises. He chose to set the film on the remote Norwegian Antarctic island of Bouvet commenting, "It's definitely
