Jackson's biographer making movie about the singer

London, March 19: Ian Halperin who penned "Unmasked: The Final Years of Michael Jackson" is working on a documentary about the late pop singer to be released in June.

Halperin's tribute documentary titled "Gone Too Soon", uses audio and video footage of the star shot before his death last June, reports contactmusic.com.

It also includes interviews with the "Thriller" singer's personal manager, chef, spiritual adviser, hairstylist, trainer, bodyguard and attorney.

According to the filmmaker, the family of the 50-year-old star, who died of acute Propofol intoxication, are aware of the project, though they do not appear in it.

The 88-minute documentary is expected to cover the star's personal life, including allegations of child abuse, but Halperin insists he is showing a "balanced tribute" to the King of Pop.

"This is the film Michael and his fans deserve," he said.

Chris Grant, the president of distributors Shine International, is confident the documentary will "eventually be known as a really important piece of the Michael Jackson saga".

"Ian's done an incredible job telling the story of what actually happened to Michael. We've teased it a bit and the reaction has been tremendous," he said.

The film will be unveiled at the MIPTV conference in Cannes, France, next month and will receive a limited cinema run in Canada and France June 25, the anniversary of Jackson's death.

There has been no confirmation about release in other countries as yet.
