"Amy," a documentary about the life of the late singer Amy Winehouse, premiered at the Cannes Film Festival. While the film is scheduled for a commercial release in July, a sneak peek of the trailer showed snippets of what went on in the Grammy Award-winner's life before her death.

The video clip shows different stages of the British singer's rise and fall from stardom, as well as hints of her dark life that saw her turn to substance abuse. Winehouse passed away in 2011 at the young age of 27 years old from alcohol poisoning.

Acclaimed filmmaker Asif Kapadia, who became famous for his work in "The Return", "Far North" and the documentary "Senna", is the man behind "Amy."

According to MTV News, Kapadia was able to access a wide collection of unreleased recordings and personal videos of the late singer, and came up with the heartbreaking documentary.

Kapadia lived on the same street as Winehouse in London. He admitted that a part of the reason he decided to do the documentary was because of his proximity to the singer when she was still alive, AP reported.

"One of my reasons for wanting to do it was, I've finally found a subject to do about home," revealed the London-born director.

His materials ranged from home videos, archive footage and more than a hundred interviews with people who were close to, and knew Winehouse. Kapadia wanted the documentary to be a fitting tribute to a lost talent -- a star that was internally tormented with doubt and depression. He also wanted the film to capture the dark side of being a celebrity in this world.

The director was quick to clarify that the documentary was not created to blame anyone for the singer's death.

"There are issues, and there are maybe things that could have been done differently," said Kapadia. "It's turning the mirror on everyone, saying, we're all slightly to blame, complicit, a part of this system - this circus - that it became."

Meanwhile, Winehouse's family is not happy with the documentary, and already expressed their decision to detach from the film, its makers, and producers. In a statement to Mail Online, her parents describe the film as "misleading and contains basic untruths."

The criticism came in light of how her family was depicted and made to look like they did not exert enough effort to help Winehouse deal with substance and narcotics abuse.

"Amy" would come out in the United Kingdom on July 3. A later U.S. release date is yet to be announced.
