"It's actually just breaking even at this point. For a film to make money it has to more than double the box office."
Say what?!? By your own statement above, "Brokeback Mountain" is already profitable. The film has earned 230% of its cost ($32.3 million/$14 million), and this has occurred while the film is still in limited release and before the huge free publicity of four Golden Globe wins.
Yeah, it's just about at break even point. Everything from here on out is profit.
