If anyone in Hollywood is foolish enough to thow a big budget at the next gay sales pitch they hear, it'll only take one or two box office flops to correct the market.
Over the long term there will be a sufficient qauantity of gay films with realistic budgets to satisfy a niche market and turn a profit.
I should have said 'gay romances' because non-erotic gay movies a la 'The Birdcage' have a much broader appeal.
