Well, as "Voyna i mir" was a fourparter, the different years are not really a wonder.
As far as I remeber "historic news" this production is called "the most expensive production in the history of the USSR". And as those vour parts all have their length, they were released in different years (at least in USSR, don't know the rest of the world).
Mine say: Part 1 in 1965, Part 2 in 1966 and Part 3 + 4 in 1967

I got no idea how the award-add on technically works. My last post was nothing else than a presumption.

But meanwhile I am not that sure if the year matters so much entered in the profile.

"Journey Into Self" (Documentary) won the Award in '69. It was released in '69 (year in my profile as well), too - but I got the see the Oscar allready for '68.

And to avoid any possible misspellings: I copied "Voyna i mir" from the Awards-Database into the profile of every single title as OT (each part on a different disc, I had the "full" OT before = Voyna i mir + name of the "episode") - but no change...

So meanwhile Academy Awards and BAFTA are up to date!
Tom, you got Mails from me, hopefully they didn't reach your Spam ;-)
