The narratives of Batman reveal an imaginary in which the hero’s archetype is filled with the “vigilante” image, which can be the main element in the cultural identification between the audience and the protagonist. In the film trilogy The Dark Knight, the main resources of this vigilant hero are the use of scientific and technological knowledge, the investigative atitude (empiric-rational), the development of his physical potential, and his ethic qualities. Based on the anthropology of imaginary from Gilbert Durand, this paper develops a “mythocritic” about the trilogy and shows how the archetypes and myths related to science, technology and a deontological ethic have a main role in the imaginary of The Dark Knight and can contribute for its success.
