How do media representations of US–Mexico border tunnels shape immigration discourse, public policy, and anti-immigrant violence? To help us think through how these tunnels are represented and often overrepresented in US media, in episode 158 of Imagine Otherwise, host Cathy Hannabach interviews Ideas on Fire author Juan Llamas-Rodriguez about his new book Border Tunnels: A Media Theory of the US–Mexico Underground. For all of their visual obscurity and inaccessibility, tunnels are hypervisible in media representations not only of the US–Mexico border region but also the bodies—both real and imagined—that are associated with the borderlands. In the conversation, Juan shares his research into how border tunnels are represented in video games like first-person shooters, television news coverage like Anderson Cooper 360°, copaganda reality shows like Border Wars, and action films like Fast and Furious. They also discuss why it is so important to think infrastructurally about media production and how designers and activists are using speculative design to reimagine what the US–Mexico borderlands are and the role of tunnels in that process. Finally, they close out the conversation with Juan’s challenge to both media makers and media consumers alike to accept responsibility for the material consequences of representation and use it to create a world where the free movement of people across and beyond all borders is celebrated and realized.
