The Koker trilogy is a series of three films directed by acclaimed Iranian film-maker Abbas Kiarostami: Where Is the Friend's House?
depicts the simple story of a young boy who travels from Koker to a neighbouring village to return the notebook of a schoolmate.
[2] Kiarostami's three films are poised between fiction and real life, opening the medium to new formal experiences.
[3] Adrian Martin emphasises Kiarostami's direct perception of the world and identifies his cinema as being "diagrammatical".
Literal "diagrams" inscribed in the landscape, such as the famous zigzagging pathway in the "Koker Trilogy", indicate a "geometry of forces of life and of the world".
