The ongoing war in Ukraine adds a timely resonance to Nenad Cicin-Sain’s documentary about the underground art and music movement that sprung up in Sarajevo during the 1990s Bosnian War. Not that it was needed, since Kiss the Future would have the same power anytime in a world perpetually marked by armed conflict. This moving and inspirational film premiering at the Festival in Berlin also boasts a commercial hook in the form of the band U2, who figure prominently in the proceedings via both archival footage and contemporary interviews with members of the band.
