The writer/director explains why he decided to make a movie for HBO about the disgraced music producer, who is now in prison on second-degree murder charges for the 2003 killing of Lana Clarkson:
Mr. Mamet says he didn't care about the trial as it was happening, but when his agent urged him to see a 2009 documentary on Mr. Spector, he became intrigued. He went from considering Mr. Spector a killer to questioning his guilt in the 2003 murder of Lana Clarkson. Watching the film, he says he found himself thinking: "There's no way he killed that girl. He got convicted of 'I don't like you."
Al Pacino will star in the HBO movie.
