Michael Jackson 'This Is It' Film Premiere Shown Worldwide

Michael Jackson's family and fans have attended the worldwide premiere of his concert documentary, This Is It.

The movie was pieced together from 100 hours of footage shot at rehearsals for the star's ill-fated comeback shows, the BBC reported.

Jackson's brothers Jermaine, Marlon, Tito and Randy, attended a star-studded screening in Los Angeles. Simultaneous premieres were held in 18 other cities.

Introducing the film, director Kenny Ortega described it as "the last sacred document of our leader and friend".

But some fans protested outside the screenings, saying the film covers up Jackson's declining health.

The dedicated fans, who have set up a campaign called This Is Not It, are accusing concert promoter AEG Live of putting too much pressure on the star during the build up to his 50-date run at London's O2 Arena.

Jackson, who died on June 25 aged 50, had spent the previous four months rehearsing in Los Angeles.
