Christopher Nolan`s Batman Trilogy, which started from Batman Begins (2005) and moved to The Dark Knght (2008) and The Dark Knight Rises (2012), is basically a superhero story to be contextualized in the post-9?11 era of the American society. In contrast to the traditional versions of Batman series both in film and the graphic novel, this trilogy represents its superthero as a floating signifier whose meaning is arbitrarily sliding into an interstice between such binary pairs as collectivity and individuation, law and justice, truth and lie heroic ideal and individual trauma. Partly influenced by Frank Miller`s apocalyptic The Dark Knight Returns series, Nolan`s trilogy reinforces the indeterminacy of traditional heroic code by a series of signifiers such as the commissioner Gordon`s manuscript for his speech on Harvey Dent`s Day, Rachel`e letter to Bruce Wayne, and the Batman`s mask. Gordon`s undelivered s[eech manuscript exemplifies how the muth of a hero is deconstructed by the contextual change of its meaning. Rachel`s letter to Bruce Wayne functions as a hinge between Wayne`s childhood trauma and his self-confidence in vigilantism. Most importantly, the batman`s mask provokes ambivalence in Bruce Wayne`s search for his true identity. Wayne`s desire to esca[e from the mask not only leads to his political failure to act beyond his individuation but also instigates his downfall into an ideological illusion of romantic elopement. Along with all these indecidable renderings of the traditional heroic code, the batman in this trilogy becomes a floating signifier to slide into open stage for the political in the American society.
