Attorneys for Robert Downey Jr. say they want more time to review the evidence against the actor stemming from his November arrest on drug charges.

Riverside County Superior Court Judge B.J. Bjork agreed Monday to delay Downey's case until Feb. 21.

One of Downey's three attorneys, Daniel Brookman, said the defense team wants to analyze drugs found after Downey's arrest and to review other unspecified evidence.

Downey's lawyers and Riverside County Deputy District Attorney Tamara Capone would not discuss the possibility of a plea bargain to resolve the case before it goes to trial.

The defense team is concerned about the events that lead to Downey's Nov. 25 arrest in the hotel room at Merv Griffin's Resort Hotel and Givenchy Spa, including the anonymous 911 call to police, Brookman said.

"We are not convinced we know the identity of that individual," the lawyer said outside an Indio courtoom.

Downey, a recent Golden Globe winner for his supporting TV role on "Ally McBeal," is charged with felony possession of cocaine and the tranquilizer diazepam and a misdemeanor of being under the influence.

The 35-year-old star of such films as "Air America" and "Chaplin" was released in August from Corcoran State Prison after serving time for violating probation on an earlier drug conviction.

If convicted of the new charges, his sentence could range from probation and drug treatment up to four years and eight months in state prison. Downey currently attends a drug-rehabilitation program, Brookman said.

Downey has not received preferential treatment during his court cases, Brookman said. "He's had a harsh time of it," including his previous prison time, and is anxious to get on with his life, the lawyer added.
