The Structure of Crystal - Kristof Zanussi 1969

A Polish film from the late 60s, early 70s.  Two friends from university meet after several years and size up each other's lives.  One has gone on to develop a successful career in physics, but has hurt others on the way up.  The other has retreated to a rural area where he runs a weather station and involves himself in daily life in the countryside.   Subtle.  Some beautiful black and white work.
