Robert Downey Jr., who was due in a Riverside Country, Calif., court this Wednesday to face felony drug charges stemming from his Nov. 25 bust in a Palm Springs hotel room, is likely to have his legal date postponed, his prosecutor, Tamara Capote, told the Associated Press. The actor, 35, charged with possession of cocaine and diazepam, more commonly known as Valium, faces more than four years in prison, should he be convicted. “We haven’t reached a disposition yet, so we’re simply going to continue (the process),” said Capote, who went on to say that a mid-march court date is now likely. Last Wednesday, it was announced by Fox TV and “Ally McBeal” producer David E. Kelley that Downey would continue on the show as the love interest of star Calista Flockhart. The announcement, which said Downey was signed on for the remainder of the season, was perceived to indicate that the network does not expect the actor’s legal troubles to interfere with his work schedule.
