Brokeback Mountain is NOT in a select-city release. It is in full, national release. They tried remaining in few theaters within a given city as possible, to create buzz, but the movie is showing in just about every major metropolitan area.
They went off their game plan when the movie expanded to 69 theaters, and saw the box office take drop badly during a week. (No, I can't be sure of cause and effect.) They then went from planning 130 theaters to opening in 217; apparently opening in any market that they could.
I imagine you're correct, but it is not playing in Dothan, Alabama.
Bearback isn't doing so well, but no matter Hollywood loves it and that is all that matters. It will win an Oscar even though it has bombed in the theaters!
It's not playing here, which is 60 miles north of Phila. and 70 miles west of NYC. The gays are probably driving out of town to see it.
