July 23 will mark the four-year anniversary of Amy Winehouse's death. Twenty days before that, a documentary detailing the singer's private life will premiere in the U.K., though not without a great amount of controversy. Directed by Asif Kapadia of Senna fame, Amy: The Girl Behind The Music will feature archive footage of Winehouse, as well as previously unreleased tracks. A 53-second clip of the film was just released, and you can watch it below. Winehouse's loved ones, however, aren't happy with the film. NME reported last month that the singer's father, Mitch Winehouse, has threatened to sue filmmakers for libel and slander. Her family also released a statement distancing themselves from the project, calling it "misleading" and "a disservice to individuals and families suffering from the complicated affliction of addiction." Winehouse's ex, Reg Traviss, also blasted the documentary in an interview with The Mirror this week. "As a biopic it’s not a valid representation," he told the British paper. "It could have been so great. They just constructed a narrative that they thought would be engaging for their viewers. And, they took the cheap, lazy option... It is very much a tabloid piece which it needn’t be." You can watch the clip below and judge for yourself.
