SHORTBUS - It's more of a polysexual film than a 'gay' one, but the ending isn't just happy, it's downright ORGASMIC!
BIG EDEN - Okay, so the whole thing is kind of a "Midwestern fairy tale", but endings don't come much sweeter than this, where the guy gets the guy and they do live "happily ever after."
ALL OVER THE GUY - At the very least, if the ending isn't jump-up-and-down happy, I'd say it's hopeful.
trick - Same with this one.
PRISCILLA, QUEEN OF THE DESERT - And this one!
JEFFREY - Though I find the lead character to be completely annoying, he and his man do make a great couple at the end, although they face an uncertain future.
BEDROOMS AND HALLWAYS - I like this movie a lot, because the 'happy ending' is so unexpected...the people who end up together are not the ones you expected to, but it all still works out.
COTE D'AZURE - It is one of those silly French sex romps, but at the end, the family that "plays together" really does stay together! And it's a musical! (Of sorts.)
ADAM AND STEVE - After what they go through together, it's nice to know that their love finally triumphs over all.
THIRD MAN OUT and A SHOCK TO THE SYSTEM - Both are murder mysteries, so things get pretty rough for both gay and straight characters. What makes the endings to both movies happy is that hunky P.I. Donald Strachey always goes home to his loving husband, Timmy.
Oh, yeah, and I just had to agree with something another poster said - 'mainstream' movies with gay themes rarely ever turn out with happy endings. So if you'd rather have that, gay independent films are a lot better, though the quality seems to vary. There's a lot of really, really, REALLY BAD gay cinema out there. But it's still worth picking through all the lumps of coal to find a few diamonds.
