Muscle (1989) - Spoken language: Japanese. Hardcoded English subs.
This film, which is an example of the Japanese "Pinku Eiga" sub-genre of gay themed movies (generally they are soft erotica with sado-masochistic themes) is also known by several other titles - "Kurutta Butokai", "Atim" and "The Madness Night", to name but three. It is probably not everybody's cup of tea, and it is only fair to warn that the quality is not the greatest (video is only 800 Kbps). But since these types of films are seen so rarely in the West, I thought that it was worth uploading.
Takeshi Itô plays Ryuzaki, an editor for Muscle magazine. He gets involved with an experimental dancer, Kitami (Simon Kumai) and at first the men's relationship is very kind and very gentle, but Kitami slowly drifts into sado-masochism and wants Ryuzaki to cut him and to hurt him. It ends in Ryuzaki cutting off Kitami’s arm and he ends up in prison for a year. But on his release he’s still in love with Kitami, or maybe just obsessed by him, and starts to search for him in the back alleys of Tokyo.
