Frank Zappa documentary - "a nuanced and authoritative portrait"

Actor and director Alex Winter got lucky - he was the first author to get access to Frank Zappa's immense vault, and he made the first authorised documentary on Zappa based on the never-before-seen footage of the legendary rock polymath he found there. "The resulting film", Guardian says, "presents a nuanced and authoritative portrait of an artist who may have spoken prodigiously to the media during his lifetime about his music and politics but who remained oddly aloof as a person".
