Saw it years ago, very good movie.
Also another excellentmovie is a Czech movie released in 2010 called Tobruk.
You should see it, very realistic ...:)

There are two versions of "The Winter War" available here in Finland: a 191 min edition (on 1 DVD, subtitles in Swedish and English) and a 264 min edition (on 2 DVDs, miniseries, seems to be without English subtitles)

I haven't seen the 125 min US cut (or mutilated) version but I've got the impression that the cut was not a very good one
