Possibly of interest to some, assessment of the film by somebody who used to work in the USSR's propaganda ministry.
The most genuine of them all are the uniformed MGB/NKVD officers. I have never seen in any foreign film such a brilliant depiction of men who combined the surly, brutal composure of professional executioners with the permanent expectation of a swift, and often painful, death from their own bosses (or just the guy next to them).
