“The Lavender Lens – 100 Years of Celluloid Queers” is a documentary by filmmaker David Johnson from 1995, I just found it on the sissydude tumblr (Johnson has uploaded it himself a while ago). The movie is a pretty extensive and uncommented montage of both famous and rather unknown queer moments of all film historical eras, starting with the legendary “Gay Brothers” from 1895, one of the first example of a motion picture. Because of it’s length I think it is a good idea to take the advice given on Best Documentary not to watch the movie in one go, but to “dip into it periodically”. Especially since the resolution of the video is not very high.
