Director Brett Morgan has done other music documentaries like “Cobain: Montage Of Heck” and “The Rolling Stones: Crossfire Hurricane”. But he’s never done anything like his latest David Bowie film “Moonage Daydream”. Morgan was not only given full approval by the Bowie estate but they also gave him access to all their archival footage. Mike Hsu talks to him about the process, the Bowie legend, and his next documentary that he says will feature an actor that the world is obsessed with. But he won’t cough up a name. You’ll have to guess.
