This article explores the ways in which Tamil film stars, so-called mass heroes such as the “Superstar” Rajinikanth, are presenced in theatrical events of their onscreen revelation and apperception. Drawing on film analysis, ethnographic accounts of theatrical reception, and metadiscourse by filmgoers and industry personnel, I focus on Rajini’s onscreen pointing gestures in highly charged moments of presencing. As I argue, these data provoke reflection on indexicality—defined by Charles Sanders Peirce as a semiotic ground based on “real connection” or “existential relation,” such as copresence, contiguity, or causality—for at issue with Rajini’s fingers is precisely the question of his auratic being and presence. Instead of analyzing performative acts of presencing through appeal to the analytic of indexicality, then, what if we interrogate those ethnographic particularities of existence and presence that constitute the ground for indexical relations and effects as such? Such an inquiry would refuse to leave indexicality as a self-evident, pregiven analytic, but instead pose it as an open ethnographic question. Opening up the question of existence and presence, as I show, allows us to unearth other semiotic “grounds” of indexicality and representation beyond those that we all too often take for granted.
