While it is Dr. Conrad Murray, who will be on trial when attorneys begin selecting a panel on Thursday, the "Thriller" singer's infamy will loom large over the proceedings.

Jackson was one of the world's most recognizable singers, dubbed the King of Pop, when he died in June 2009, at age 50. He also was known to have battled an addiction to painkillers, and Murray's attorneys had hoped to present evidence of his past drug use at the trial.

But in an obstacle for the defense, Los Angeles Superior Court Judge Michael Pastor barred testimony from a half-dozen doctors whom Murray's attorneys had indicated in court papers would portray Jackson as drug-dependent.

"The deck is, for various reasons, stacked against the defense here," said Stan Goldman, a professor at Loyola Law School in Los Angeles.

Jackson stopped breathing at his Los Angeles mansion on June 25, 2009, in what authorities say was an overdose of the powerful anesthetic propofol and various sedatives.

Murray, who pleaded not guilty to the charge of involuntary manslaughter, has admitted giving Jackson propofol, a drug normally used for surgery, as a sleep aid.

During a series of court hearings earlier this year defense attorneys suggested that when Murray was out of the room, Jackson could have given himself a large, fatal dose of the drug, possibly by swallowing it.

Murray faces up to four years in prison if convicted.

As for choosing an impartial jury, legal experts say it will be impossible to find anyone who knows nothing of Jackson. Some will adore him, while others will abhor him. So attorneys will have to work to find the most unbiased jury possible under the circumstances.

"It's going to be like a Ouija board, it's going to be guess work," Goldman said.

After a jury panel is selected, the trial will be recessed until opening arguments begin the last week of September.

Jackson's family has faithfully attended all the court hearings in the case, with his mother, Katherine, 81, often sitting with his father, Joseph, 83.
