A documentary chronicling Vogue editor-in-chief Anna Wintour’s preparations for the 2007 fall-fashion issue and the passion that Grace Coddington, a former model turned creative director and the only person who dares to stand up to Anna Wintour, has for the highly-regarded fashion magazine.

A profile of Vogue’s imperious editor Anna Wintour, and a fly-on-the-wall procedural on the making of the magazine, R.J. Cutler’s documentary unveils the real-world inspiration for The Devil Wears Prada. It’s a sharp, funny, and impossibly glamorous peek into the high-flying world of haute couture.
