Italy - 1989
Director - Luigo Cozzi
There is not much Luigi Cozzi material out there, he only directed some 15 films and several of those are very hard to get in the US, this being one. I wish I could see because it looks totally idiotic but fun. That's not a surprise, it is Cozzi, possibly the only guy who could make a horror film about a syphilitic violinist.
Incidentally, Paganini was one of the "characters" Klaus Kinski developed and was obsessed with, regularly raving like a madman "in character" even off screen if Herzog is to be believed.
