LOS ANGELES (AP) - "Michael Jackson's This Is It" premiered to high praise from fans who applauded at each number as though they were at a concert and marveled as the singer stepped nimbly through his moonwalk and other signature moves.
Jackson, 50 when he died last June, kept pace with backup dancers half his age during rehearsals for such hits as "Thriller," "Billie Jean," "Beat It" and "Human Nature."
The film was shot as Jackson prepared for a marathon concert stand in London that never happened. "He looked better than he did when he was 30," said Jessica Childs, a 21-year-old aspiring dancer who caught the Los Angeles premiere. "His voice stood out."
Most of the material was intended for Jackson's private use, but it now serves as the last bow of a performer who ruled the pop charts in the 1980s and later retired to a reclusive life amid allegations of child molestation.
The mood at simultaneous premieres around the world Tuesday and Wednesday was tearful yet celebratory. At the Los Angeles premiere near the arena where much of the rehearsal footage was shot, "This Is It" director and longtime Jackson collaborator Kenny Ortega introduced the film to the audience, calling it the "last sacred documentation of our leader and our friend."
"It was touching. Well done. It was beautiful," said Casey Gosh, 24, who was invited to the premiere by a friend. "It told his story. You really felt like you knew him. It was his final performance."
The footage revealed just how elaborate and demanding Jackson's comeback run of 50 planned concerts last July would have been. One segment showed how Jackson would have made a grand stage entrance inside a mechanical spider.
Another, intended as a 3-D film accompaniment on "Thriller," featured an expansive graveyard set. Outside before the premiere, Ortega wiped away tears as he greeted dancers and celebrity guests, including Paula Abdul.
Among others attending were Will Smith, Jennifer Lopez, Paris Hilton, Neil Patrick Harris, Katy Perry and Motown Records founder Berry Gordy Jr. Ortega said he expected audiences would be most surprised by "the intimacy. It's unguarded and raw and real, and Michael is there and available to us all, and lovely and kind."
Said Abdul afterward: "It was beautiful. It was sad. It brought you closer to who he was as a person." It was the biggest cinematic blowout ever for a music film as "This Is It" opened for paying customers immediately after the premieres, with evening and midnight screenings in North America to middle-of-the-night and morning showings in Europe, Asia and elsewhere.
Distributor Sony, which paid $60 million for the film rights, opened "This Is It" in 99 countries. It expands to 110 territories this weekend.
"I was tossing and turning with nervous feelings all night. Michael Jackson is a hero in my life, and I cannot wait to see the final shot of Michael," said Noh Kyeong-ae, a 34-year-old accountant, sobbing at a movie theater in Seoul, South Korea.
The simultaneous showings around the globe were anchored by a star-studded premiere at the Nokia Theatre, a concert venue across the street from Staples Center, where many of Jackson's rehearsals - and his high-profile public memorial - were held. Four of Jackson's brothers - Jermaine, Marlon, Tito and Jackie - attended. "It's showing what a perfectionist he was," Jermaine Jackson said. Performances in the film included a medley of Jackson 5 hits the singer originally performed with his siblings. Michael Bearden, musical director and associate producer of "This Is It," said making the film was the most "bittersweet" project of his career, but he was happy "the world will see (Jackson's) triumph."
"I know he would have liked it," Bearden said. "We considered Michael in every aspect of the movie. We were with him every day for the last three or four months of his life at least, so we know he would have liked what we did."
The film captures Jackson dressed with customary flamboyance, his fashion flourishes including military epaulets, sequins and gold-spangled pants. Jackson backup dancer Misha Gabriel said the film is "such an honest and raw look at the creative process that at times it makes me think that maybe he wouldn't want people to see so much of the creative process before it was finalized. But I think that's the beauty of the film."
"It's Michael becoming great, perfecting his perfection, if that makes sense," said fellow dancer Nick Bass.
The plaza in front of the Nokia Theatre was transformed into an elegant red-carpet arrivals area, with a dozen crystal chandeliers, displays of Jackson's past costumes and "This Is It" spelled out in giant letters. Jackson memorabilia was on sale inside, from T-shirts proclaiming "I Love MJ" to key rings reading "King of Pop."
Some of Jackson's family and friends saw "This Is It" in advance. Elizabeth Taylor, a longtime friend of the pop star, posted her thoughts Monday on Twitter.
"It is the single most brilliant piece of filmmaking I have ever seen," she wrote. "It cements forever Michael's genius in every aspect of creativity."
The 77-year-old actress added that she "wept from pure joy at his God-given gift" and urged her fans to see the film "again and again." Clocking in at one hour, 51 minutes, the film was culled from more than 100 hours of footage that captures Jackson as a showman, a mentor coaching backup talent and a goodwill ambassador.
Near the film's end, Jackson and the crew hold hands as he gives them a pep talk about the London shows.
"It's a great adventure," Jackson tells his colleagues. "We want to take them places they've never been before. We have to bring love back into the world."
