Michael Jackson's life is the subject of a new documentary, produced by the singer's long-time friend and concert promoter David Gest.
"The Life of an Icon" is tracing Jackson from his breakthrough years to his rise to fame as a solo artist through to his sudden death.
At the film's world premiere in London Gest promised it would give fans a new insight in to the late "king of pop's" life.

"I think you'll find out who the man behind the music was and you'll see a different side to him. This is a film when people watch it they go 'I didn't know that, I didn't know that, I didn't know that'."
Speaking about his memories of the singer, Gest said Jackson's final years were lonely and difficult.

"Even his family and his closest friends really couldn't get to him. His number would change, you'd try to call him and you'd have to go through so many people and there was all this security and people that came and went. It was pretty sad the last few years."
The documentary features interviews with Katherine Jackson, siblings and friends and colleagues.
Jackson's sister Rebbie said the film and the on-going trial of Jackson's physician Dr Conrad Murray were bringing back memories.
Murray has pleaded not guilty to involuntary manslaughter over the singer's death.

"I am happy I did what I did with this because I felt it was something that was necessary. I felt that I owed him this much and not only that, I felt I wanted to do it for myself for therapy as well."
Jackson's brother Tito was also in London.
In the documentary he discusses what the family went through during a 2005 child molestation trial where his brother was eventually acquitted on all counts.

"He was a person that just wanted to help people -- if you needed something or you were in poverty or whatever he wanted to make a difference in your life because he grew up in poverty and things of these nature, so he wanted to give some of the underprivileged people some of the things that he didn't have as a kid."
Aside from the documentary Gest is also involved in a world tribute tour to Jackson which kicks off in Britain next spring.
His projects are part of a series of Jackson-related events which have been taking place since the singer's death in June 2009.
