Alien vs. Predator (also known as AVP and stylized as ΛVP) is a 2004 science fiction action film written and directed by Paul W. S. Anderson, and starring Sanaa Lathan, Raoul Bova, Lance Henriksen and Ewen Bremner. It is the first installment of the Alien vs. Predator franchise, adapting a crossover bringing together the eponymous creatures of the Alien and Predator series, a concept which originated in a 1989 comic book written by Randy Stradley and Chris Warner. Anderson, Dan O'Bannon and Ronald Shusett wrote the story, and Anderson and Shane Salerno adapted the story into a screenplay. Their writing was influenced by Aztec mythology, the comic book series, and the writings of Erich von Däniken.
