You all seem pretty superhumanly adept at helping people with this unique kind of problem, so I humbly submit to your greater minds for help with this matter.
I am desperately seeking:
Very rare movie that is scifi/dystopian/experimental/surreal. It's like Stalker meets el Topo meets Holy Mountain meets Alphaville meets Delicatessen meets Hard to be a God, like Kurosawa, Tarkovsky, and Lynch had a kid together. It was color, possibly Russian, and I don't really remember the decade but want to say 60s or 70s, though could easily be more recent. It is VERY rare, there is only one crappy partial print of it, and that is what the youtube version is from. Lot of wide shots in a surreal wilderness, winter settings, strange bleeding saturation in some shots. Crazy costumes. Seriously one of the strangest films I've ever seen and my favorite films are strange/weird ones.
If you've ever seen what you're thinking of on a "best weird movies" or "you've never seen this!" list, that's NOT it. I don't think this film even has a cult following of ten people. It's an actual rare gem. Have been looking through selections at 366 Weird Movies and not found it yet (btw the way most of those titles are exactly the kind of not-actually-rare movies this film is definitely not).
