A 163-minute version of the film competed in the main competition of the 2009 Cannes Film Festival . The Cannes cut lacked much of the finished film 's sound design , and some visual effects were not fully in place . Noé said about the version : " the film was like a baby of three months . I took it out of my belly to show it , flattered by festival general Thierry Frémaux 's invitation , but it was still in gestation . So I had to put it back into my belly , that is to say to tweak many details . " Festival screenings of subsequent versions followed throughout the year , including the Toronto , Sitges , London , and Stockholm international film festivals . The final 154-minute cut premiered at the 2010 Sundance Film Festival . At the Cannes premiere , the film had alternatively been listed with the French title '' '' ' Soudain le vide '' ' '' , which means " Suddenly the void "
