Stacey examines the body-horror movies Alien: Resurrection and Species in light of Jean Baudrillard's apocalyptic proclamations about cloning and "the hell of the same," and she considers the art-house thrillers Gattaca and Code 46 in relation to ideas about imitation, including feminist theories of masquerade, postcolonial conceptualizations of mimicry, and queer notions of impersonation. Turning to Teknolust and Genetic Admiration, independent films by feminist directors, she extends Walter Benjamin's theory of aura to draw an analogy between the replication of biological information and the reproducibility of the art object. Stacey suggests new ways to think about those who are not what they appear to be, the problem of determining identity in a world of artificiality, and the loss of singularity amid unchecked replication.
