Paul Calori was born in 1978 and studied literature and cinema in Ecole Normale Supérieure (Paris), dedicating his master’s thesis to the films of writer Georges Perec. Kostia Testut was born in 1980 and studied linguistics and communication in Sorbonne-Nouvelle (Paris), writing his master’s thesis on Guy Debord and Situationalism. Both would go on to La Fémis, the French national film school, in 2002. Paul specialized in directing and making short films, with Les Heures Creuses (2006) selected for festivals. Kostia, who specialized in screenwriting, directed the short film Label Rouge (2003) and was mentored by Jean-Claude Carrière for his graduation script. Together, they co- wrote and directed the musical short Le Silence des Machines (2007) for the Franco-german TV channel Arte, which garnered praise in short film festivals. They spent several years transposing the idea of the short (a musical set in a factory threatened by downsizing) to the feature film format, and this effort gave birth to Footnotes (Sur Quel Pied Danser), first released in France in July, 2016. Since leaving La Fémis, both have continued working on individual projects.
