Calendar

Not Atom Egoyan's most 'story-driven' film, but his best from a purely aesthetic/cinematic perspective. His use of non-linear chronology, repeated scenes that slowly give way to understanding, and long drawn out takes that let you really start to feel the moment (how many viewers start to notice the slight differences in the various sheep, or look for their birthdays on the pages of the wall-calendar?) puts this film close to the level of Tarkovsky, Angelopolous, Bresson, etc.

While "Exotica" and "The Sweet Hereafter" are, understandably, his better known films (and good ones at that), "Calendar" works even better as the full realisation of theme and emotion using all the elements of cinema working in conjunction.
