This was an interesting, 3 hour watch by the Soviet director Andre Tarkovsky it's a semi-biographic film on the life of Andrei Rublev, famous Russian Icon Painter of the early 15th Century.
Slowly shot, black and white (1966), a minimal of dialogue, - the background dialogue, when it's happening, isn't translated, but strangely moving.
A note, it's 3 hours long, and - in being filmed and set in a different era, Tarkovsky set a cow on fire, clubbed a dog to death and shoved a horse off a stairwell then stabbed it - not a film the SPCA would endorse, and in parts difficult to watch. Reminding me of "The Holy Mountain", where Jodorowsky killed hundreds of rabbits and blew up hundreds of toads. Unnecessarily cruel, and for people that seem to have a fair bit of Spiritual - ?? - well, it's a hard reconcile.
Then, given the time it was set in - early 1400's, when entire villages were razed by Tartars, raped and pillaged, where the King or Prince might as well decide to do the same, when the Plague was passing through Europe and killing 1/2, 2/3 people, comparing the age where death was of no consequence and seldom grieved, of no account, compared to now, where every war - Gaza - Israel, Rawanda, Ukraine, every plague - by comparison - is inconsequential and every life is held of immense value (unless you're killed by the cops). A - to the Western Mind - almost inconceivable point of view.
This is not to excuse the current state of affairs, but we've never had it so good, and it will be a long, long time before ever we have it so again.
