"Secret Identity Crisis" follows the trajectory of the breakdown of the Cold War consensus after 1960 through the lens of superhero comic books. The superhero comic books developed by Marvel, because of their conscious setting in the contemporary world, and because of attempts to maintain a continuous story line across and within books, constitute a system of signs that reflect, comment upon, and at times have interacted with the American political economy.Physicist Bruce Banner, caught in the nuclear explosion of his experimental gamma bomb is transformed into the rampaging green monster, the Hulk. High school student Peter Parker, bitten by an irradiated spider, gains the powers of the spider and becomes Spiderman. Reed Richards and his friends are caught in a belt of cosmic radiation while orbiting the Earth in a spacecraft and are transformed into the Fantastic Four. While Stan Lee suggests he clung to the hackneyed idea of radioactivity in creating Marvel's stable of superheroes because of his limited imagination, radiation and the bomb are nonetheless the big bang that spawned the Marvel universe.The Marvel superhero comic that came to dominate the comic book industry for most of the last five decades was born under the mushroom cloud of potential nuclear war that was a cornerstone of the four-decade bipolar division of the world between the US and USSR. These stories were consciously set in this world and reflect the changing culture of Cold War (and post-Cold War) America. Like other forms of popular entertainment, comic books tend to be very receptive to cultural trends, reflect them, comment on them, and sometimes inaugurate them. This groundbreaking study focuses on a handful of titles and signs that specifically involve political economic codes, to reveal how the American self was transformed and/or reproduced during the late Cold War and after.
