Amy Winehouse’s family has criticised an upcoming documentary about her life.

The late singer’s family have claimed that the film, titled Amy, is misleading. In a statement, a spokesperson for the Winehouse family said they “would like to disassociate themselves from the forthcoming film about their much missed and beloved Amy”.

A spokesperson for the family said: “They feel that the film is a missed opportunity to celebrate her life and talent and that it is both misleading and contains some basic untruths. There are specific allegations made against family and management that are unfounded and unbalanced.”

Mitch Winehouse said the film did not represent his involvement in his daughter’s life. “I was there every day,” he told BBC Newsbeat. “And if I wasn’t there – because I was working or I was away somewhere or she was away somewhere – she’d phone seven times a day. And there’s no sense of that in the film and that’s what’s disappointing.”

The film was “tainted”, he added. “My disappointment is that the film could have been terrific. They’re going to look at this film and know the film’s been tainted. And there’s absolutely no reason for it to have been that way.”

The filmmakers have responded to the criticism, claiming that they approached the project with “total objectivity” and insisted the story it tells is “a reflection of our findings” from around 100 interviews with people who knew Winehouse.

Amy is directed by Asif Kapadia (Senna) and will be shown in a special screening at this year’s Cannes film festival. [via The Guardian]
