Well, it seems as if Anna Wintour’s Letterman stint paid off.

Opening in six New York City screens this past weekend, The September Issue raked in $240,078. With $40,013 per screen, R.J. Cutler’s Vogue documentary nabbed the second-best per-theater average of any 2009 film and the fifth-best documentary opening in history (right behind Paul Provenza’s The Aristocrats).

With Wintour going so far as waiting in a common line to catch the film, let’s hope that it scores more when it opens in limited screens across the US on September 11.
