Amy Winehouse's immediate family were initially willing to work with the film's producers and director, having heard about the success of their earlier documentary, Senna (2010). They granted the filmmakers access to hours of archive footage of Amy and her family, as well as giving the filmmakers' their blessing to interview Amy's family and friends. However, they - in particular, Amy's father, Mitch Winehouse - soon began to feel they were being misrepresented in the documentary, that the negative aspects of Amy's life were receiving much more attention than the positive, and that footage had been edited in order to produce an inaccurate narrative of Amy's story, especially the last three years of her life. Mitch Winehouse has said that Amy's fans should consider seeing the film for the rare, previously unseen, archive footage of his daughter, but should pay no attention to the film's general portrayal of her, which he has labeled "preposterous". Even after the film was nominated for an Academy Award as 'Best Documentary', Mitch Winehouse tweeted on 14 Jan. 2016: "Still hate the film though."
After watching this film, James Hetfield of Metallica was inspired to write a song called "Moth into Flame".
First documentary distributed by A24 to be nominated for an Oscar.
