Amy Winehouse’s friends and admirers turned out to honour her memory at the premiere of Amy, the documentary film based on her life, where they paid tribute to her personality and musical talent.

The Back to Black singer, who died of alcohol poisoning in 2011 at 27, is the subject of the film based on archive footage and interviews with more than 100 people who were involved in her life.

Director Asif Kapadia, who previously directed the successful biopic Senna, said: “It’s about addiction, it’s about the pressure of fame, it’s about love, it’s about family, it’s about friendship, it’s about creativity. The film is about just introducing you back to the real person.”

He added: “People maybe who came in late will maybe only remember the girl who was not in a good way on stage, or a bit out of control in Camden. But there was so much more to her before that. And the film is really showing you that person and understanding where the records came from and celebrating her for what an amazing artist she really was.”

Nick Shymansky, who worked as her first manager when she was 16, called her one of the most amazing people I ever knew, adding: “Her legacy is that she made incredible music, she moved a lot of people.

“We’ll see what her true legacy is in 20 years, but I think she was just a really authentic, original person.”

Lauren Gilbert, a close friend of Winehouse, said: “Her music speaks for itself, but if you put that aside, her as an individual – which not many people pay attention to – she’s an amazing human being, and everyone should know that.”
