A-Listers Flock To Watch Jackson's This Is It

Los Angeles came to a standstill on Tuesday night (27Oct09) as Hollywood A-listers joined the JACKSON brothers for the premiere of the King of Pop's concert rehearsal movie THIS IS IT.

The L.A. launch of the tour documentary - featuring Michael Jackson's final stage performances before his death in June (09) - 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.

Jermaine Jackson promised fans they'd be blown away - but urged people to remember the footage was shot during rehearsals and not a full-blown performance.

He explained, "You are going to see preparations for what would have been one of the greatest shows ever. You are going to see him going through the motions, not giving 100 per cent."

Jackson's mother Katherine and his three children were believed to have watched a private showing of the film at a screening at Sony Studios on the same night.
