I've come across this film by chance, because I would never have looked for it, otherwise. People like me, who know a little the Soviet cinema, know that this is not the usual Soviet stuff. You think you are watching a Billy Wilder or Howard Hawks movie in Russian! Quick and ironic dialogues, a good plot, not a moment of rest, a litlle of social satire, and that kind of humour which today is very rare to find: subtle and understated, but nonetheless effective.
The actors are all good, and you see that they believe in what they are doing. Yuriy Yakovlev became later a star in the USSR. The director is particularly inspired and makes no mistakes.
It should be dubbed in other languages and known abroad.
