The late, intermittently great singer Amy Winehouse is going to be the subject of a new documentary. Senna director Asif Kapadia is developing a new film about the bouffant-sporting Brit who died in 2011. The project, currently in development at Focus Features, will be presented to movie buyers at Cannes next month. It will be co-produced by Playmaker Films and Universal Music, meaning a guaranteed soundtrack tie-in and big posthumous sales for the singer. And it will all be done in a very respectful way, of course.
