Gay and Gayer

Think gay this fall; then think Hollywood. Tinsel town is literally awash with films; back to back that keep portraying gay characters, so much so you could be forgiven for thinking American cinema had turned a corner and become "seriously independent".
Watching the BBC's 'Talking Movies' the other day I can now rattle off for you a roll-call of mostly, gay flicks which you might see opening at cinemas far far away from you.(Capote, Brokeback, Transamerica..... and the list goes on and on and on...)
The real challenge, as one critic on the programme pointed out, lies in getting a mostly straight audience to buy tickets to such movies let alone develop an appetite for gay romanticism in mainstream cinema; something not too many studios are willing to take a call on,either.
Much has been made of openly straight leads for gay characters but you would think this one's a slam-dunk - no openly straight actor, not even in his gay frame of mind would be gullible enough to imagine audiences taking, what they hear or see in make believe world of cinema, at face-value, so on that count I doubt if straights playing gays deserve any extra brownie points at all.
Besides, for some of us at least, straights acting gay simply does not cut the muster : gays playing gay can bring an uncommon intensity on screen which, at best, can leave most straight actors groping to get a handle on. There's nothing quite like hearing it straight from the horse's mouth; if you see what I mean. Besides casting for gay characters isn't exactly what you might call a "level playing field" either, with there being a dearth of gay talent, save Chad Allen's to be tapped into .
Now that brings us to improvisations on films belonging to this bonafide genre of gay film making for a straight audience. What could Ang Lee have possibly done differently, to make Brokeback twice as great a film it is touted to be?
Well, for starters, they could have given him free rein in telling the story of a fledgling romance between a Texan cowboy and an Afro-Caribbean farm hand or to have it filmed down under; capturing an Aussie life guard from Bondi Beach on heat for his Aborigine lover-boy, as alternative themes for Brokeback.
Much water has flown under the bridge of gay rights activism at a safe remove from race issues that we can no longer ONLY embrace 'homogeneity of homosexuality' - there's every need to jazz read heterogenize things up a little, every now and again, and how well we can jazz it up too!
Having come this far, Hollywood ought to give producers and script-writers the fiat to develop storylines and film on location in prisons, army barracks(CENTCOM's included) besides closeted religious fiefdoms the world over, where the concept of gay love blossoming, is wholly conceivable. I am willing to bet you my best friend's Vertu that that would indeed make for some compelling cinema.
Am I right or am I right?
