Evidently the first installment in a series that didn’t continue, this instructional film shows idle twelve- and sixteen-year- old brothers learning how to improve their surroundings by painting an old door. With the narrator giving step-by-step instructions, the boys go through the processes of sanding, applying primer, and mixing different types of paint. Whatever its educational value, the film’s quiet enthusiasm for its subject also reflects Kiarostami’s own interest in woodworking.
