Heard them talking about it on the radio today.
Apparently, someone decided it was too hot for regular distribution, so it went the "art" theater route.
The result was the 3rd highest ever revenues/screen, behind only "Spiderman" and I forget what else.
From Wikipedia:
"Audiences embraced the film, which played to sell-out crowds in many of its U.S. showings on its opening night. This led to a largely unexpected first-day gross of $9,050,000[9], wildly surpassing its competition despite having been shown on only 837 screens, far fewer than the competition which is shown on over 3,000 screens.
Over the opening weekend of the film, it unexpectedly got to No. 1 on the weekend with a total of $26.9 million, beating its competitors, Flushed Away and The Santa Clause 3: The Escape Clause. The film's opening weekend's theatre average was an estimated $31,511, topping over Star Wars Episode III: Revenge of the Sith yet behind Pirates of the Caribbean: Dead Man's Chest and Spider-Man.

I gotta see it; the synopsis was hilarious
