This chapter explores the double nature of the vampire through a reading of the film Underworld, one of many contemporary narratives that picture the vampire as militarized and inherently Western. The chapter is especially concerned with the ways that the vampire as Western champion has been appropriated by what has been theorized as the Military Entertainment Complex (Lenoir) or the Military-Industrial-Media-Entertainment Network (MIME-NET) (Der Derian). The military entertainment complex can be understood as a coming together of what Eisenhower termed the military-industrial complex and the entertainment industry, fuelled by the revolution in information technology and by US neo-imperial ambitions. In this way, the chapter seeks to explore the relationship between the dual nature of the vampire, the military entertainment industry, US foreign policy after 9/11 and what is perhaps best described as the technological/imperial desire that informs so much American popular culture today.
