In the second part of Kiarostami’s lauded “Koker” trilogy, a filmmaker went looking for the stars of his previous film in a remote, earthquake-devastated mountain region, learning about life from the people he met along the way. In the trilogy’s magnificent concluding chapter, Kiarostami looks at the making of the second film, Life and Nothing More…, from the same remove, evoking an Iranian variation on Truffaut’s seminal movie-about-moviemaking, Day For Night. A lovely comedy of moviemaking errors, Through the Olive Trees revolves around the romance between a local stonemason, cast as an actor in the film-within-the-film, who continues to doggedly pursue his leading lady long after the cameras have stopped rolling.
