Vogue is a church and Anna is Pope. The September issue is the biggest issue Vogue releases in the year: 'September is the January in fashion' goes one of the many sound bites this documentary throws up. Kicking off months before the issue goes to press, an issue that sees Sienna Miller as cover girl, this documentary is meticulous in depicting the events in the run up as Wintour is in putting the magazine together. Wintour is very hands-on, choosing every article of clothing and picking every image that goes into the magazine. This micro-management attitude clashes with her best friend and colleague - fashion director Grace Coddington. The September Issue is an interesting and sometimes fascinating peek into the cutthroat world of fashion (an intern is encouraged to be nasty because 'if you're nice, you'll lose') and what it takes to put together one issue of Vogue.
