This chapter aims to investigate the concepts of communitas in Polish culture after 1968 by analyzing the post-March comedy film Rejs (The Cruise, 1970), directed by Marek Piwowski. The analytical focus lies on processes of community-building: on inclusion and exclusion through (mis)communication. Political philosopher Roberto Esposito put forward the concepts of communitas and immunitas as intertwined mechanisms strongly related to biopolitics and communication. While the former signifies open, integrative social exchange, its latter, closing counterpart stands for social decontamination and isolation. Therefore, regarding Piwowski’s film I would like to address bodily performances and communication as processes of bonding and/or cutting social bonds.
