It's one of the weirdest courtroom images ever captured: legendary record producer Phil Spector looking like a member of the Hair Bear Bunch, sporting an enormous frizzy Afro wig while on trial for murder.

Now Oscar-winning actor Al Pacino is the one wigging out, as he dons a similar hairpiece for a scene in the upcoming HBO movie, "Phil Spector." Next to Pacino, and almost unrecognizable herself thanks to dowdy clothes and hair, is Helen Mirren as Spector's attorney, Linda Kenney Baden. Famed playwright David Mamet wrote and directed the film.

The movie became controversial in 2011 due to rumors that it is sympathetic to Spector, who was convicted of Lana Clarkson's 2003 murder in 2009. Mirren defended the film when a group of Clarkson's friends protested, saying, "Lana was obviously a really, really lovely woman and, quite rightly, her friends are worried that she will be dissed and she is certainly not dissed in our story at all."

"Phil Spector" airs March 24 at 9 p.m. on HBO.

Phil Spector's lawyers have asked the U.S. Supreme Court to review his murder conviction, arguing that his constitutional rights were violated by the trial judge. According to attorney Dennis Riordan, Superior Court Judge Larry Paul Fidler became a witness for the prosecution by offering his opinion on an expert's testimony during the trial.

Spector, who is currently serving 19 years to life in prison for the 2003 murder of actress Lana Clarkson in his Los Angeles mansion, has failed in previous attempts to overturn Judge Fidler's ruling. The California Supreme Court shot down an appeal on the decision twice over earlier this year.

The legendary record producer's attorneys ultimately hope to obtain a third trial for their client. His first trial, back in 2007, was declared a mistrial after jurors deadlocked.
