MJ's "This Is It" will be released at the end of October

MJ's "This Is It" will hit the big screen worldwide for a two-week limited engagement this fall.

Named after the series of 50 sold-out London concerts that were to begin last month, "This Is It" will capture the King of Pop Michael Jackson at work, rehearsing and collaborating with singers, dancers, choreographers and special-effects creators in preparation for the planned public performances. The film will draw from more than 100 hours of behind-the-scenes footage taken from April through June of 2009.

Sony Pictures has pushed the worldwide debut to Oct. 28 due to the anticipated demand, according to a press release.

Kenny Ortega, Jackson's director and creative partner for the "This Is It" tour, will direct the motion picture.

"While the concerts would have been the greatest shows in the history of music, our film will provide a historic event for Michael's fans to see for themselves the genius that he was and the creativity, talent and imagination that the entire cast devoted to create the greatest concert that never happened," AEG Live President and CEO Randy Phillips said in a press release.

Jackson, who died June 25 after suffering cardiac arrest, will be laid to rest in a private ceremony in Glendale, CA, Aug. 29, on what would be his 51st birthday.
