The number of heterosexual males interested in seeing "Brokeback Mountain" is infinitesimal, but still higher than the combined I.Q.'s of the movie's, er, backers.
Not necessarily.
The movie's budget was a piddling $13 million. Did the actors and crew brown bag peanut butter and jelly sandwiches ? The financial loss on this movie will be tolerable from Hollywood standards.
The core problem is that this film is demanding that we view the act of sodomite sex as beautiful and romantic. Heterosexual males find it disgusting. That is why in opportunistic homosexual relationships among normally heterosexual males (prison, British public school, ships at sea) the stronger male penetrates the weaker male but is never penetrated himself.
