Nikita Mikhalkov - Pyat vecherov aka Five Evenings (1979)

Quote:
Based on the play by Alexander Volodin. The set is the 1950s. The tangible world of an old communal apartment is recreated onscreen with an incredible accuracy, every thing capturing the flair of the time. The stylized visuals, the curious objects, the amusing inhabitants, so charming and exotic… There are all the marks of the ‘retro’ style, which is always ‘in’. The actors Ludmila Gurchenko and Stanislav Lyubshin succeeded in conveying everything that they couldn’t say openly. The finale allows for different interpretations. Hence the emotions evoked by this impeccably made melodrama appear to be even more poignant.Once Alexander and Tamara were in love. But the war had separated them… Twenty long years after, they meet again, but they lack the courage to admit that their feelings are still alive. Unable to overcome their pride, they try to convince each other that both are doing just fine…

Andrei Yermash - Konets vechnosti AKA The End of Eternity (1987)

Eternity is an organization and a place which exists outside of time.

It is staffed by humans called "Eternals" capable of traveling “upwhen” and “downwhen” within Eternity and entering the conventional temporal world at almost any point of their choice. Collectively they form a corps of Platonic guardians who carry out carefully calculated and planned strategic minimum actions, called Reality Changes, within the temporal world in order to minimise human suffering as integrated over the whole of (future) human history.

Andrew Harlan, an expert in executing Reality Changes, falls in love with a non-Eternal as he comes to understand his part in a paradoxical scheme to secure the creation of Eternity by sending a young Eternal back in time with the mathematical knowledge to make it possible...
