Michael Jackson's biographer is making a movie about the star's final days.

Ian Halperin – who penned 'Unmasked: The Final Years of Michael Jackson' – has been working on a tribute documentary entitled 'Gone Too Soon', which uses audio and video footage of the late star shot before his death last June.

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 Ian insists he is showing a 'balanced tribute' to the 'King of Pop'.

He added: "This is the film Michael and his fans deserve.'

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'.

He said: "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."

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 on June 25, the anniversary of Michael's death.

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