This chapter explores the transmission of affect in cross-media storytelling and the potential ideological effects of this process. Traditionally, research on transmedia storytelling has excluded adaptations but, following Dena (Transmedia Practice, PhD, 2009) and Hutcheon (A Theory of Adaptation. Routledge, 2006), this chapter suggests that adaptations are not just retellings but potential sources of additive comprehension (cf. Jenkins, Transmedia 202: Further Reflections. Pop Junctions (blog), 2011). The chapter brings together critical affect studies and transmediality to ask whether and how textual affects travel when a text moves from one medium to another, and what happens to the social intelligibility of the affect. The chapter explores the legibility of fictional flat affect and the modes of its transmediation to the screen based on the example of Don DeLillo’s novel Cosmopolis (2003) and its 2012 screen adaptation by David Cronenberg. The chapter argues that the novel and the film can be read as a politically potent example of additive transmedial narration that helps us grasp contemporary social affects.
