"I'll have to investigate the topic of "Necrorealism", was it mainly based in Russia or is it more of a Worldwide movement?"

So far I've only come across it being referenced as a Russian movement which began in the Leningrad art scene. Sokurov's former student, experimental filmmaker Yevgeniy Yufit, was one of its founders. More Info.

I believe the UK DVD has burnt-in subs.
