showcase, Saturday, 8.30pm ★★★★ This telemovie starring Hollywood heavyweights Al Pacino and Helen Mirren opens with the most ridiculous disclaimer. We’re told ‘‘this is a work of fiction . . . a drama inspired by actual persons in a trial, but it is neither an attempt to depict the actual person, nor to comment on the trial or its outcome’’. So why on earth call the telemovie Phil Spector? The title suggests we are to be presented with a story essentially based on fact, but the disclaimer arouses suspicion writer-director David Mamet has not let the truth get in the way of a good story. That, however, does not stop Phil Spector from being one of the most compelling pieces of TV you’ll see this year. It explores the client-attorney relationship between legendary music producer Phil Spector (Pacino) and defence attorney Linda Kenney Baden (Mirren), who represented Spector during his first trial for the 2003 murder of Lana Clarkson. Clarkson, the jury was told, died after Spector pulled the trigger on a gun he’d placed in her mouth. His only hope of getting off at trial is Kenney Baden, who has ‘‘reasonable doubt’’ about his guilt.
