An HBO biopicture about record producer Phil Spector's murder trial distorts the truth but may be a way to shed some positive light on his 19-year prison sentence, his wife said.

Rachelle Spector told Rolling Stones the television network had "the opportunity to make an amazing film" but instead Al Pacino's portrayal of her husband, a famed Hollywood producer, turned out to be "cheesy."

If anything, she said perhaps the film will sway the public's opinion about Phil's murder conviction tying him to the 2003 shooting and death of Lana Clarkson.

"Regardless of how I feel about the cheesy portrayal of my husband and the gun-waving, the yelling and the crazy stuff, what they did get right was the forensic evidence that could set my husband free," she said.

Clarkson, a struggling actress, met Phil on Feb. 3, 2003, at the Sunset Strip club where she worked as a hostess, according to The Los Angeles Times. Hours later she was found dead of a gunshot wound in the mouth in the producer's home in Alhambra, Calif. Phil at the time reportedly said, "I think I killed somebody."

His first murder trial in 2007 resulted in a jury unable to agree on a verdict (the result is a mistrial) but Phil was found guilty of second-degree murder in a second trial held in 2009. The 73-year-old is currently serving a sentence of 19 years to life in a California prison.

The HBO biopic is an "exploration of the client-attorney relationship" during Phil's trials for the murder, according to the network. Pacino plays Phil and Helen Mirren stars as his defense attorney, Linda Kenney Baden. Phil Spector, directed by David Mamet, premieres Sunday.

Rachelle also attacked Pacino's acting skills, saying he does not depict Phil "accurately."

"If they had wanted to do that, they would have actually met the man himself. They would have wanted to know his voice inflections, his mannerisms, even his thought process," she said. "...Or what he was going through mentally or emotionally when the trials were happening. They had the opportunity to make an amazing film, what with the actors and the money involved."

Phil and Rachelle are fighting for appeals and in 2012, the Supreme Court declined to review the conviction. The couple married in 2006.

The Times noted that the disclaimer opening the film reads, "This is a work of fiction. It's not 'based on a true story.' It is a drama inspired by actual persons in a trial, but it is neither an attempt to depict the actual persons, nor to comment upon the trial or its outcome."
