In his previous films, Hacerme feriante (2010) and Embodied Letters (2015), Julián D’Angiolillo managed to go deep inside two universes that, even though they take place in front of everyone, remained invisible and inscrutable, as though they were subterranean—that of La Salada fair and of the authors of political graffiti in walls. For Ongoing Cave, his third work, the director goes back underground, this time in a literal manner, in order to reveal the mysteries of speleology, the science that studies caves and caverns. Italy, Slovenia, Cuba; antiwar bunkers; an exploring, revolutionary ballerina; an electronic party in which the stalactites and stalagmites dance under the flashlights. Everything is part of the ecosystem of tunnels and people that D’Angiolillo connects on screen, through images in which what lies still comes to life.
