Has anyone seen this, or have any information about it?

Also called "The Long Days," it was supposedly directed in part by Terence Young (Dr. No, The Valachi Papers). I remember seeing clips of this on a Frontline episode years ago, but as far as I can tell no English language copy has ever surfaced. There's some scattered info about it on the web, but no information that wasn't already covered in the Frontline piece.

Any info about it or where to get a copy of it would be greatly appreciated.
