I think that's it.
HERE IS THE BLURB FROM MOJO: "Fahrenheit's $27,558 per theater average ranks as the second highest all time for a wide release (adjusting for ticket price inflation knocks it down to No. 11) and the best of 2004, ahead of The Passion of the Christ's $27,554 and Shrek 2's $25,951. However, they were super-saturation releases playing at 3,043 and 4,163 theaters respectively -- the lower the theater count, the easier it is to have a high average as the release isn't diluted by less populous locations with lower ticket prices."
Which makes it easy to do, when you show it in a few small theaters.
I know there have been a few threads on FR mentioning this point, but I've been too busy fumigating and sprinkling holy water my computer after Moore's name appears on it. So I don't have them book marked.
