Yeah... I visited Florence too, back in 1989 when there was less security surrounding David. You could even take pictures of him then. He wasn't under copyright until more recently.
In regards to The Brotherhood, I think there are too many gay vampire movies, many milked before like Dracula's Daughter and The Hunger especially.
I could also see a late night airing of Kinsey (2004), but here is a key problem: this retrospective isn't supposed to be about sex. (This is exactly why so many conservative politicians are on the war path against gay rights, because they can't distinguish the sex-part from anything else.) Movies presented should be more about relationships overall and acceptance by others for being different. Negative representations should be shown strictly from a historical perspective, like with Reflections of a Golden Eye representing the era and all of its restrictions.
For James Whale, Gods and Monsters (1998) is a natural fit and I should have included it. Nothing that would bother most viewers apart a fleeting peekaboo group nude-by-the-pool shot in a dream/memory sequence. They could follow this with The Bride of Frankenstein (1935). Most of these recent movies would be rated PG or PG-13 instead of R had the censors not been so concerned about non "heteronormal" activity.
Fassbinder's Fox and His Friends is a great all-around picture for this kind of thing. Although I do still consider it more R rated material and, thus, a late night show, all of the nudity is confined to a brief bedroom scene and a bathhouse that doesn't show any actual physical contact between patrons. We saw a nude scene from this already on TCM when it aired a documentary series a few years back called The Story of Film: An Odyssey with Robert Osbourne interviewing the compiler/director Mark Cousins beforehand.
However this movie is all about the story of one man trying to be accepted by others, but struggling in a German gay culture-within-a-culture that shares the same prejudices and social superiority status mirroring the rest of society. The film did get criticism for being too negative a portrait, especially since the gay rights movement was only getting started in 1974 when it was made and many activists were still pushing for more optimistic portraits of gay life then. I especially like the scene when the two guys can't allow an Arab friend... er, hustler maybe?... into a Holiday Inn in Morocco for racial reasons, despite the head guard being the same race! (That memorable bit part was by Eli Hedi ben Salem of Ali: Fear Eats the Soul.)
