The son of actor Oscar-winning actor Michael Douglas could face life in prison for selling large amounts of an illegal drug over a three-year period before his arrest late last month, court records show. Cameron Douglas, 30, a sometimes actor who appeared with his father and grandfather Kirk Douglas in “It Runs in the Family,” is accused of selling tens of thousands of dollars worth of methamphetamine, according to a complaint unsealed this week. Rebecca Carmichael, a spokeswoman for the US Attorney's Office in Manhattan, would not comment on whether Douglas had applied for, or been granted, bail. Douglas faces a mandatory minimum of 10 years in prison and a maximum period of life for two counts of possessing and distributing forms of methamphetamine.
