Clouds of May, the second feature of Turkish filmmaker Nuri Bilge Ceylan, struck some viewers as belonging to the school of Kiarostami, a mistake they wouldn't make with his masterful third feature. An industrial photographer in Istanbul (Muzaffer Ozdemir) who hasn't recovered from his busted marriage finds himself the reluctant host of a country cousin (Mehmet Emin Toprak) looking for work. Ceylan uses this slim premise to build a psychologically nuanced relationship between the men, as an uncomfortable domestic arrangement leads to irrational spats. The narrative, capped by a brief bad dream and the capture of a mouse, isn't always legible, but it feeds into a monumental, luminous visual style like no other. The nonprofessional leads won top honors at Cannes; shortly afterward Toprak died in an auto accident. In Turkish with subtitles. 110 min.
