The Friends of Lana Clarkson group will be staging a silent vigil outside the Los Angeles County Museum of Art's Bing Theater to protest the "inaccurate and hurtful portrayal of historical events at the expense of people still alive today" in the film about the music mogul's murder trial.
Spector was found guilty of murdering the actress at his Alhambra, California mansion and sentenced to serve 19 years to life behind bars.
Edward Lozzi, who was Clarkson's former publicist and friend, tells Wenn, "The film portrays Lana as being responsible for her own death, which is totally unacceptable to decent society, law enforcement, the L.A. Court system, legitimate forensics and the L.A. District Attorney's Office."
David Mamet, the screenwriter of the Phil Spector film, is expected to attend the screening along with Linda Kenny Baden, Spector's attorney, who is portrayed onscreen by Helen Mirren.
Lozzi, who will be part of the protest, adds, "David Mamet has ignored the pleas of Lana Clarkson's friends to consult on the script in order to guarantee that Lana Clarkson and the trial for her murder were portrayed accurately and without the stench of artificial doubt that Spector was innocent, thereby portraying Clarkson responsible for her own death. All requests were ignored."
News of the protest comes a day after Spector's wife Rachelle revealed she too is unhappy with the film, which will air in the U.S. later this month (Mar13).
She told news show Entertainment Tonight, "They (producers) have him as a foul-mouthed megalomaniac and they depict him as a minotaur - like he draws people into his labyrinth and he locks them in and won't let them out... This guy couldn't hurt a fly."
Rachelle Spector is campaigning to free her husband, insisting he's innocent of the charges and should not have been convicted for Clarkson's murder.
