It was available in the US on DVD, but from the looks of it it’s out of print. But used ones should be floating around. Unfortunately all the torrents looks like their dead. Once Demonoid went under years back, and their backlist of torrents vanished, the major venue for tracking that sort of shit down went with it. And nothing replaced it. There’s just a lot of stuff like this that just hasn’t made it to digital platforms and with discs out of print there’s no regular way to view them.
So haunt Ebay? Or if you’re near one of the few cities with an artsy fartsy video store left I’d head there. I’ve seen repertory showings advertised as part of film festivals.
