It may appear tiny to the human eye, but there is no denying that the insect kingdom -- as captured by the filmmakers behind this documentary -- is as dramatic, action-packed and beautiful as any other. Indeed, using a variety of film techniques and an inspired score, the moving image of a beetle pushing a ball of dung takes on the mythic quality of Sisyphus with his boulder. Meanwhile, endless caterpillar caravans suggest, amazingly, the rhythm of modern highways during rush hour.
