Finnish and Japanese don't really sound the same when spoken, but structurally the words are pretty similar and at least I found it far easier to pronounce than Hungarian, which is actually related to Finnish. There is a story of a Finnish band called Leningrad Cowboys doing an ad in Japan, and them having to dub it because the band members pronounced Japanese too well, and nobody would've believed they were the genuine article :)
When I was in Prague in 1994 there seemed to be a whole subculture of Leningrad Cowboys. They were everywhere. I saw maybe a couple of dozen of them around the city. Few punks, no goths (and goths were EVERYWHERE that year) just these guys with the gravity-defying hair and unfeasible footwear. Leather jackets, usually, rather than the suit coats in the film, but definitely that look and the utterly deadpan facial expressions as well.
Way back when BoingBoing was a print magazine, there was an article written by Rudy Rucker about a sci-fi film that he, Robert Anton Wilson and Terrence McKenna starred in. Twenty years later, I get to see it on YouTube. Here it is. .
