A handheld camera focuses on a green door, while a whispered female voice asks who will be behind it. When it opens, there is a younger version of Amy Winehouse, cigarette in hand and looking typically dishevelled.
It is 2006 and the singer, then 23, is holidaying in Majorca with friends just prior to the release of her second album, Back to Black, which will shoot her to international stardom. These are images from an exclusive documentary  Amy (The Girl Behind The Name), directed by Asif Kapadia.
Winehouse is showing the apartment to her friend, the one who is doing the recording, and they pass from lounge to bedroom, to bathroom, to the balcony and then to the terrace, where a cat appears.
The young woman is happy and talkative, constantly joking and allowing us to see the intimacy she shared with her closest friends.
This is the leitmotif of  Amy: to show the other side of one of the most successful artists of recent years,
Her life was a roller coaster once her voice began to attract followers from across the globe to her concerts.
Her drug addiction and her tortuous relationship with Blake Fielder played out in front of the world’s gaze.
The circus came to an end on 23 July 2011 at the age of 27.
Critics have spoken favourably of the documentary, and it is considered to be a strong candidate for an Oscar nomination.
