Michael Jackson's 'This Is It' film premieres globally
Jackson brothers plus Will Smith and Katy Perry attend Los Angeles screening
The film was pieced together from footage of the late singer's rehearsal sessions for his London O2 Arena residency, which took place at the Los Angeles Staples Centre.
Jermaine, Marlon, Tito and Randy Jackson, the singer's brothers, attended the premiere that took place at a cinema opposite the Staples Centre, with the likes of Will Smith, Katy Perry, Jennifer Lopez and Berry Gordy Jr, founder of Motown Records, also attending, reports BBC News.
Tickets for the film have sold well internationally, although some fans have been critical of it.
Some have set up a protest group, This Is Not It, claiming promoters AEG put too much pressure on Jackson during rehearsals, which resulted in his ill health.
