Srdjan Dragojevic - Lepa sela lepo gore AKA Pretty Village, Pretty Flame (1996)

The plot, inspired by real life events that took place in the opening stages of the Bosnian War, tells a story about small group of Bosnian Serb soldiers trapped in a tunnel by a Bosnian Muslim force (it is based on an article written by Vanja Bulić). Through flashbacks that describe the pre-war lives of each trapped soldier, the film describes life in former Yugoslavia and tries to give an answer (though, from Serbian point of view) as to why former neighbours and friends "turned on each other".
The film won accolades for superb direction, excellent acting and brutally realistic portrayal of the war in former Yugoslavia. It was also the first Serbian film to show the Serbian side of the conflict involved in atrocities and ethnic cleansing - the title of the film is an ironic comment on the protagonists' activities in a Bosnian Muslim village.
