(Yahoo News) LOS ANGELES – “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.” Four of Jackson’s brothers — Jermaine, Marlon, Tito and Jackie — attended, saying afterward that seeing their brother on film filled them with love and pride. “It’s amazing to see him up there doing his thing,” Jackie Jacksonsaid. “To see him up there doing his performance like that has brought a lot of tears to my eyes, sitting there watching him. Because I love him so much. That’s why I keep this with me at all times in my pocket. It’s a little token of him,” he said, pulling out a white-glove key-ring fashioned after one of his brother’s best-known accessories. “It was closure for me,” said Marlon Jackson. “And it was a moment where I just felt his spirit inside of me. And that made me feel good.”
