The obscure Russian "Necrorealism" art movement, which emerged in the 1980s, doesn't even rate a page on Wikipedia. Based on the video below, it seems to have been an excuse for a bunch of Russian guys to make low-budget zombie movies in the forest. Though movies without a semblance of a plot.
The slightly grandiose, academic name belies the fact that the movement was actually a small group of experimental-artists from Leningrad (now St Petersburg) who emerged in the 80s under the leadership of the artist/experimental filmmaker, Evgeny Yufit.
Having got their hands on a lavishly illustrated forensic pathology textbook for inspiration, their initial output was comprised of photos of themselves in zombiesque make-up. Then followed performances... events that passersby or passengers were guaranteed to observe with horror. Later they began to use film as medium, and established an underground film studio.
