PARIS: A documentary on the life of Amy Winehouse will feature unseen footage of the late star, the company handling its sale at the Cannes film fest said. Focus Features International said it would be taking the as yet untitled film to next month’s Riviera movie extravaganza. The five-time Grammy award-winning singer died in 2011 from accidental alcohol poisoning. She had suffered years of drug and alcohol addiction. “Using unseen archive footage, the film will show through her own words the genius in Amy’s art.”–AFP
