Although many of Sala’s works address personal histories—his own and those of others—their themes of trauma, loss, and recovery are universal. Using tropes of both documentary and fictional filmmaking, Nocturnes (1999) approaches these themes in an uneasy exploration of insomnia and personal isolation. The film offers a brief but telling glimpse into the lives and psyches of two men Sala met while studying art in Turcoing, France: Jacques, who collects and obsessively cares for thousands of fish, and Denis, who copes with disturbing memories of his service as a United Nations peacekeeper in Bosnia by playing violent video games.
