WORK OF FICTION

The HBO film starts with a disclaimer saying it is a work of fiction "inspired by actual persons in a trial, but it is neither an attempt to depict the actual persons, nor to comment upon the outcome."

It tells how Baden became intrigued by Spector and the challenges of defending him. She considers how to raise reasonable doubt in the minds of the jury while the defense team wrestles with whether Spector should take the stand.

As his attorneys consider that Spector might hurt his own cause, Spector reminds them of his accomplishments. In one scene, he tells Baden: "The first time you got felt up, guess what? You were listening to one of my songs."

The real-life Baden told reporters on Friday that, as Spector's attorney, she couldn't tell Mamet about any conversations with her client. Instead, they were left to the playwright's imagination.

Baden said she felt the forensic evidence against Spector did not prove he killed Clarkson, who was found shot to death in the foyer of Spector's home hours after the pair met in a nightclub. Spector denied murdering Clarkson but did not testify at either trial.

Pacino said he didn't try to perfectly mimic the real-life music producer or meet with him, though he did watch video footage of his statements around the time of the murder trial.

"I would sit for hours just looking at Phil talking about things," said Pacino, speaking via satellite from New York.

Mirren said on Friday her biggest challenge was finding the right tone to play a character in the unconventional world that Spector seemed to inhabit.

"It's like a strange dream you are having," Mirren said. "The nature of Phil Spector and the life that he lived encouraged that. He seemed to live in a permanent dream."
