The Alien Quadrilogy is a nine-disc boxed set devoted to the four Alien films. Although previously available on DVD as the Alien Legacy, here they have been repackaged with vastly more extras and with upgraded sound and picture. For anyone who hasn't been in hyper-sleep for the last 25 years, this series needs no introduction, though for the first time each film now comes in both original and "special edition" form. Titles include: Alien, Aliens, Alien 3, and Alien: Resurrection.
