I think you'll be surprised by the number of gay theme flicks "out" there.
For a wonderful film historical resource guide on G/L/B/T films check out the book "THE CELLULOID CLOSET" Homosexulaity in the Movies, Revised Edition by Vito Russo. Title is also available on VHS/DVD.
For and extensive list of movie titles search on the "Earths Biggest Movie Data Base" at
www.imdb.com search under the genre: Gay/Lesbian. I also highly recommend you check out the various G/L/B/T film festivals. Here in Phoenix every March the community comes out by the thousands in support of the "OutFar" film festival.
www.outfar.org Food for thought/Commentary: Until recently, commercially distributed gay themed feature films the U.S. has lagged behind the more enlightened, sophisticated producers/directors and audiences across the Big Pond and at the BBC.
A few of the titles in my collection: My Beautiful Launderet, Another Country, Eating Out, Doing Time on Maple Drive (Originially aired on FOX TV Network) Eban and Charley, It's in the Water and Jeffery.
As an *Aussiewannabe I higly recommend:
Priscilla Queen of the Desert, The Sum of Us, and Beautiful Thing.
Enjoy,
