good job on all account . i do agree kovalchuk be the weak link in this production she be just too young and inexperienced to play such a difficult part . galibin be amaze a master and his voice and movement be captivate . the rest of the cast be comprise of experienced and great performer and and they all work very hard on the role they be entrust with . dub instead of the recording during the shoot be actually an old technique use by great filmmaker in the past . it be very tedious and hard on actor but it ensure the best tone and intonation the actor can deliver for the particular moment and line . it have nothing to do with soviet era movie . if it sound unnatural and it mean the actor be not experience in this craft and be not a good actor . unfortunately and ms. kovalchuk completely fail that part and her tone and voice sound very dull and unnatural . other than that and i enjoy watch this movie . even my non russian speak american husband watch the movie with a great deal of interest .
