"This Is It," the documentary based on video of Jackson's last weeks of preparation for his never-to-be comeback tour, became the biggest grossing documentary, with box office sales of $263 million just months after his death.

If Michael were alive today

Michael Jackson would be approaching 56 this summer had he not died. His autopsy revealed that Jackson was in good health when he overdosed from a combination of the propofol and sedatives while preparing for his comeback tour.

Would Jackson have completed his tour, which called for shows around the world after the first 50 concerts in London? Would he still be performing? Would his comeback have lifted him from the huge debt that burdened his last years?

An entertainment industry expert testifying for Jackson's mother at the AEG wrongful death trial said he was "reasonably certain" Jackson would have performed 260 shows around the world as part of his "This Is It" tour. He would have earned $890 million over the three years of concerts in Europe, Asia, South America, North America and Australia, said Arthur Erk.

An AEG expert witness, however, disagreed. He testified that even if Jackson had not died on June 25, 2009, he may not have survived the London shows because of his use of propofol to treat his insomnia.

Erk testified that he would have expected Jackson would do four more world tours before his 66th birthday.

Michael Jackson planned to focus on making movies after his "This Is It" tour, according to trial testimony. His first discussions with AEG Live -- which led to the concert contract -- were about making a film about Egypt's King Tut with AEG, witnesses said.

Jackson planned to buy a large estate in Las Vegas with part of his profits from his three-year contract with AEG Live, according to testimony. But did he plan to live in Las Vegas and perform there, instead of traveling on tour in his later years?

Whitfield and Beard, the former bodyguards who worked for Jackson most of his last two years, said that while Jackson said he wanted to do shows in Las Vegas, he would have found a permanent home elsewhere.

"He likely would have stayed out of the country," Beard said.

Jackson, who had endured the child molestation trial in California, believed people in the United States were "mean" to him, Whitfield said. "Those were his words. 'It's so mean here and how wonderful people are in other countries.' The way I took it, the dude is out."
