An HBO spokeswoman said Friday that the network is working with Spike Lee and Murphy on the project, though she said it's in the early stages of development. Lee would direct the project, and Murphy would play Barry. Lee did not immediately respond to requests for comment.
Nearly 10 years ago, HBO also bought the rights to "Dream City" for a different project, but it was never produced.
In 1990, during Barry's third term as mayor, he was videotaped smoking crack cocaine in a hotel room during an FBI sting operation, an episode that drew worldwide attention. He eventually served six months in federal prison on a misdemeanor drug possession conviction and was elected again to the D.C. Council in 1992. Barry won a fourth term as mayor in 1994. He returned to the Council in 2004 and continues to represent one of the city's poorest wards.
Barry has declined to talk publicly about the HBO project. A telephone call to his council office was not immediately returned.
