Graham Baker's engaging science fiction buddy-cop movie, is a very clever and entertaining motion picture. It concerns a massive saucer-shaped alien spaceship that lands in the California desert with some 300,000 genetically engineered extraterrestrial slave laborers abroad, with no way to leave. After a quarantine period, the humans who call them "Newcomers," allow the aliens to assimilate into American culture in southern California where they work, play and live along with humans. But because the Newcomers posses superior intelligence and near superhuman strength, there is a percentage of people in the human community who discriminate against them and call them "Slags." A bigoted, wise-cracking, old school LA Police Detective named Matthew Sykes, played marvelously by James Caan, watches his partner viciously gunned down by some Newcomer thugs during a store robbery, and vows to avenge him. Walled out of the investigation of his partner's murder directly, he elects to accept the first Newcomer detective, Samuel Francisco, played wonderfully by Mandy Patinkin, Sykes renames him George, and hopes that his new partner will uses his ties in the Newcomer community to lead to his partner's killer. It is not long before Sykes discovers that is partner's killing was part of a larger conspiracy involving a corrupt Newcomer official, William Harcourt, superbly played by Terence Stamp, and the distribution of a highly addictive drug that use to control the newcomers. A great concept, with lots of imaginative touches, but it's the chemistry between Caan & Patinkin that makes this movie work, and they are terrific together. Solid direction by Graham Baker, with impressive cinematography by Adam Greenberg. Followed by a TV series and three made-for-TV movies. Highly Recommended.
