Los Angeles (CNN) -- Michael Jackson's health deteriorated so badly in the last weeks of his life that he couldn't perform some of his trademark dance moves, according to evidence presented in his family's lawsuit against a concert promoter.
Jurors in the wrongful death trial Friday watched a comparison of Jackson's performance of "Billie Jean" from 2001 with rehearsal video from June 2009, when he was preparing for his "This Is It" comeback concerts.
"I have watched him deteriorate in front of my eyes over the last 8 weeks. He was able to do multiple 360 spins back in April. He'd fall on his ass if he tried now," production manager John "Bugzee" Houghdahl wrote in an e-mail to AEG Live CEO Randy Phillips on June 19, 2009.
Show director Kenny Ortega sent Jackson home from a rehearsal that night because of his strange behavior.
"He was a basket case and Kenny was concerned he would embarrass himself on stage, or worse yet -- get hurt," Houghdahl wrote. "The company is rehearsing right now, but the DOUBT is pervasive."
Randy Phillips: He's president of AEG Live, the concert promoter that contracted with Michael Jackson for his "This Is It" comeback shows set to start in London in July 2009. The Jackson lawsuit says Phillips supervised Dr. Conrad Murray's treatment of Jackson in the weeks before his death, making the company liable for damages. E-mails between Phillips and other executives showed they were worried about Jackson's missed rehearsals and sought Murray's help getting him ready. 
Katherine Jackson: Michael's mother, 82, was deposed for nine hours over three days by AEG Live lawyers. As the guardian of her son's three children, she is a plaintiff in the wrongful death lawsuit against the company that promoted Michael Jackson's comeback concerts. 
Prince Jackson: Michael's oldest son is considered a key witness in the Jacksons' case against AEG Live, since he is expected to testify about what his father told him about the concert promoter in the last days of his life. Prince, who turned 16 in February, is becoming more independent -- he now has a driver's license and jobs. 
Paris Jackson: Michael's daughter, who turned 15 on April 3, is on the list of witnesses and was questioned by AEG Live lawyers for several hours on March 21 about her father's death. Paris is an outspoken teen who often posts messages to her 1 million-plus Twitter followers. 
Blanket Jackson: Although AEG Live asked the judge to order Blanket, 11, to sit for a deposition, and he is one of the four plaintiffs suing them, Michael's youngest son will not be a witness in the trial. His doctor submitted a note to the court saying it would be "medically detrimental" to the child. 
Kevin Boyle: The Los Angeles personal injury lawyer is leading the Jackson team of at least six attorneys in the wrongful death suit against AEG Live. One of his notable cases was a large settlement with Boeing on behalf of two soldiers injured when their helicopter malfunctioned and crashed in Iraq. 
Perry Sanders, Jr.: Katherine Jackson's personal lawyer is helping steer the Jackson matriarch through her relations with her son's estate, probate court and the wrongful death suit. He is also known for representing the family of Biggie Smalls in their suit against the city of Los Angeles over the rapper's death investigation. 
Marvin Putnam: He's the lead lawyer for AEG Live, defending against the wrongful death suit. The primary focus of his legal practice is "media in defense of their First Amendment rights," according to his official biography. 
Philip Anschutz: The billionaire owner of AEG, parent company of AEG Live, is on the Jacksons' witness list. He is the force behind the effort to build a football stadium in downtown Los Angeles to lure a National Football League team to the city. He recently pulled his company off the market after trying to sell it for $8 billion. 
Tim Leiweke: He was recently fired as AEG's president as Philip Anschutz announced he was taking a more active role in the company. The Jackson lawyers say Leiweke's e-mail exchanges with executives under him concerning Michael Jackson's health are important evidence in their case. 
Joe Jackson: Michael's father, 84, is on the witness list for the trial and may testify. The Jackson family patriarch, who lives in Las Vegas separately from his wife, has suffered several ministrokes in the last year, which some close to him say have affected him. 
Paul Gongaware: The AEG Live co-CEO worked closely with Michael Jackson as he prepared for his comeback concerts. He testified at Dr. Conrad Murray's criminal trial that he contacted the physician and negotiated his hiring at the request of Jackson. AEG lawyers say it was Jackson who chose, hired and supervised Murray. Gongaware knew Jackson well, having been tour manager for the singer in previous years. 
Kenny Ortega: He was chosen by Michael Jackson and AEG Live to direct and choreograph the "This Is It" shows. Ortega, who choreographed for Jackson's "Dangerous" and "HIStory" tours, testified at Dr. Conrad Murray's criminal trial that "Jackson was frail" at a rehearsal days before his death. 
Dr. Conrad Murray: He was Michael Jackson's personal physician in the two months before his death, giving him nightly infusions of the surgical anesthetic that the coroner ruled led to his death. Murray, who is appealing his involuntary manslaughter conviction, has sworn that he would invoke his Fifth Amendment protection from self-incrimination and refused to testify in the civil trial. There is a chance that Murray will be brought into court from jail to testify outside the presence of the jury to allow the judge to determine if he would be ordered to testify. 
John Branca: He's one of two executors of Michael Jackson's estate. Branca was Jackson's lawyer until about seven years before his death. He said Jackson rehired him just weeks before he died.

Who's who in Jackson trial The e-mail chain -- titled "trouble at the Front" -- is key evidence in the trial in which Jackson's mother and three children contend AEG Live is liable for the singer's death because it negligently hired, retained and supervised Dr. Conrad Murray.
Murray, who was convicted of involuntary manslaughter in Jackson's death, told police he used the surgical anesthetic propofol to treat Jackson's insomnia so he could be rested for rehearsals. The coroner ruled Jackson's June 25, 2009, death was caused by an overdose of propofol.
AEG Live lawyers argue it was Jackson who chose and supervised Murray and that their executives had no way of knowing about the dangerous propofol treatments being administered in the privacy of Jackson's home.
Houghdahl's e-mail came during a "highly charged time" when there was doubt the show would be ready for its London debut in July of that year, Phillips testified Friday.
Phillips met with Dr. Murray, Michael Jackson and Ortega at Jackson's home a day after getting the Houghdahl e-mails, according to testimony.
While Jackson lawyers argue that meeting was intended to pressure Murray to make sure Jackson was ready for rehearsals, AEG lawyers contend Dr. Murray assured producers nothing was wrong with him.
AEG's lawyer showed jurors a clip Thursday of Jackson performing several non-consecutive 360-degree spins while rehearsing his song "Billie Jean" on June 5, 2009.
Phillips described them as "multiple 360 spins," although conceding he was not a choreographer.
Jackson lawyers, in their rebuttal Friday, showed the jurors the side-by-side comparison of the routine in 2001 and the one weeks before Jackson's death that was seen in the "This Is It" documentary made from rehearsal video.
"Anywhere in the movie does it show Michael Jackson doing multiple 360 spins?" Jackson lawyer Brian Panish asked Phillips.
"No," Phillips said.
