Fahrenheit 9/11--sold out

A group of us were going to try and see Fahrenheit 9/11 tonight, but the two West side theaters showing the movie here in Seattle sold out all prime time showings yesterday. That's quite surprising for a documentary, a movie that isn't something like Lord of the Rings or Spiderman. Controversy is good business.
I wonder if it's selling out in more Republican regions of the country?
