That is EXACLY what they are doing. This thing has only opened to about 300 theaters and BTW the per-screen average is dropping PRECIPITOUSLY (see http://www.the-numbers.com/movies/2005/BRKMT.php).
It was a cheap enough movie that it might break even (which is really a loss, since you have to have receipts about 3X a movie's cost just to break even) since a small number of ultra-liberals (and of course gays) will watch it, but that will be it.
If "success" = "getting nominated for awards" then Bareback Mountain might score. If "success" = "making money" it will be a dismal failure.
