Robert Downey Jr. may have to clear his busy film schedule for some jail time.
The actor's probation was revoked Friday after his drug counselor said that Downey violated a court order by using drugs and alcohol last month.
A Dec. 8 hearing was set to determine Downey's penalty. He could be sent to jail for as much as three years or ordered to a drug treatment facility.
After a string of drug arrests, the 32-year-old Oscar-nominated star of "Chaplin" has been working steadily. He's in "One Night Stand," opening next month, and two films coming out next year -- "The Gingerbread Man" and "Two Girls and a Guy." He just finished filming "U.S. Marshals" and is about to start work on "Blue Vision."
