In these grim days, when Russia is still conducting a monstrous aggression on its neighbor Ukraine, there is only one good news coming from that country. Probably the most prominent film studio in the USSR, Mosfilm, has published a lot of its most famous and critically-acclaimed films on YouTube for free. They even included six films of Andrei Tarkovsky: The Mirror, Stalker, Solaris, Andrei Rublev, and Ivan's Childhood.
