Adventures of a Dentist (1965)

This is story about a dentist with the talent of painlessly extracting teeth, and what happens to him as a result of being naturally good at his job. It is told with humour (much of it quite subtle, almost surreal, and in the background - imagine a street scene where everyone on the sidewalk on one side of the road walks in just one direction, and on the other side in the other), poignancy, and a frequent breaking of the 4th wall between the movie and the audience (think of what happens in Shakespeare's plays, and you'll be close). It also features some songs by Novella Matveyeva, a famous Russian singer-songwriter (her songs are sung by the leading actress).
