Director Oliver Stone is under arrest for investigation of drug possession and driving while intoxicated. He was pulled over at a police checkpoint in Beverly Hills, California, Friday night after police say he showed signs of alcohol intoxication. Police say they also found drugs in his car, but wouldn't say what kind. In 1999, the filmmaker pleaded guilty to drug possession and no contest to driving under the influence. He was ordered into a rehabilitation program. Stone won Academy Awards for directing in 1989 for "Born on the Fourth of July" and in 1986 for "Platoon," which also won the Oscar for best picture.
