If you are interested in film, I recommend reading Remembered Branches: Towards a Future of Korean Homosexual Film by Jooran Lee. The article, from the journal Queer Asian Cinema: Shadows in the Shade Volume 39, is available almost in its entirety Google books. Here is the abstract:

Korean cinema has long labored under an imported Confucian homophobia which, through its effects if not its causes, seems to mirror the Western conception of the closet. Recent cinematic developments in Korea, including a queer film festival in Seoul, are slowly but surely beginning to change that. Using as primary texts the recent Korean gay film Broken Branches and the long-forgotten lesbian film Ascetic: Woman and Woman, my essay hopes to serve as a set of introductory remarks on a queer Korean cinema culture whose surface has only just been broached.

The article mentions films that were released in the 1970s that the author includes in the Korean queer film archive. I've been trying to get a copy of Broken Branches for a while and now I have a bunch of more films I'll be looking for. Anyone know where I can get copies? (Preferably with English subtitles)
