Tomislav Gotovac

For IMDb onlookers, main actor in this underground movie is an artist, Tomislav Gotovac - he is world famous, in early '80ties he ran in the main street of Zagreb in nude, kissing the ground as part of his performance (similar to his role of streaker in this student flick). Unfortunately he didn't receive much attention in communist Yugoslavia nor in "free" democratic Croatia, he died in poverty and sick. Before he died he changes his name to Lauer.

I remember in Musem of modern art in Zagreb, there is his exhibition - there was dice, but instead of number 1-6, on each side there is word - "pain". It impressed me very much.

Sex trivia:
Thanks to this banned film, he was the first man who showed his tinky winky in Yugoslav cinema. I believe this was the first time that two men were french kissing in front of camera. Also, years later he filmed himself having sex, and he was the first person who filmed penetration in Yugoslav cinema. First filmed erection in ex-yu goes to film W.R. Mistery of organism.
