(REUTERS) - A new film about late British singer Amy Winehouse is misleading, her father said on Monday, adding the six-time Grammy Award winner's family was disassociating itself from the production.

Mitch Winehouse said he was not happy with the way the makers of "AMY", which will screened at the Cannes Film Festival next month, had portrayed him.

The film was directed by Asif Kapadia, who won a BAFTA for his documentary "Senna" on the late Formula One racing driver Ayrton Senna.

Amy Winehouse, seen as one of the most talented musicians of her generation, died from alcohol poisoning in July 2011 at her London home, aged 27.

The singer, known for hits such as "Rehab" and "Back to Black" had struggled with drinking and drug problems throughout much of her career.

Winehouse praised the use of video of a younger Amy, shown laughing and being funny but criticised the film's narrative. Winehouse said the film missed details such as an interview the singer's fiance Reg Traviss. The "AMY" filmmakers defended the documentary.

"When we were approached to make the film, we came on board with the full backing of the Winehouse family and we approached the project with total objectivity," they said in a statement, adding they had conducted around 100 interviews for the film. "The story that the film tells is a reflection of our findings from these interviews."
