Elem Klimov - Sport, sport, sport aka Спорт, спорт, спорт (1970)

From allmovie.com

What makes an athlete compete? How can he be made to endure the gruelling training most sports require? In this image-rich combination documentary and poetic drama, participants in sports including foot-racing, wrestling, speed-skating, swimming and gymnastics are seen in their daily lives and in all stages of training and competition. Their regimens are contrasted with the efforts of ordinary people to train some life into their limbs as they exercise to lose weight, or, as aging people, in order to stay active. In one episode, a marathon runner competing on a hot summer day in Philadelphia literally runs himself to death, and in a later dramatic re-enactment, medieval warriors hold a competitive joust. As one image piles upon another in this unique film, answers to questions about competition begin to suggest themselves.

Elem Klimov - Agoniya (Агония) AKA Agony (1981)

Synopsis:
A wide-scope panoramic view of Russia in 1916. The country is in its third year of war which seems to never end, with police rule, hunger and devastation at their peak. All this plays out against a background of luxury and corruption at the court, where the agonizing power still entertains hopes of coping with “the rebels”. The courtiers have a presentiment of the collapse of the Russian autocracy. Fear, despair and blind belief in Providence make a fertile ground for the “great” starets, adventurist Rasputin, who is a friend of the royal family and has gained mastery over the Czar and his ministers. The filmmakers used newsreels of the 1917 Revolution… This controversial historic drama was released twice: in 1975 and, after a number of changes, in 1985. RUSCICO offers the film’s 1985 version.
