This looks like the most interesting documentary since... ever. Think the "real" Devil Wears Prada. Anna Wintour, the intensely private editor in chief at American Vogue, is giving the public an inside look at what really goes on behind the scenes of the country's fashion bible. It is sure to do well, as documentary films go, following the blockbuster success of the 2006 film that made the notoriously villainous fashion mogul a household name.
