Los Angeles came to a standstill on Tuesday night as Hollywood A-listers joined the Jackson brothers for the premiere of the King of Pop’s concert rehearsal movie This Is It.

The film – featuring Michael Jackson’s final stage performances before his death in June – has been cut from 80 hours of videotape filming the star’s last few days of rehearsals for the concerts planned for London’s O2 arena in July.

Last night’s Los Angeles launch coincided with the worldwide release of the film, which premiered across 15 cities including London, Seoul, South Korea; Johannesburg, South Africa; Rio De Janeiro, Brazil and Berlin, Germany.

The tragic superstar’s brothers Jermaine, Tito, Jackie and Marlon walked the red carpet alongside Will Smith, Jennifer Lopez, Katy Perry and Paris Hilton.
