“A World Not Ours” is a passionate, bittersweet account of one family’s multi-generational experience living as permanent refugees. Now a Danish resident, director Mahdi Fleifel grew up in the Ain el-Helweh refugee camp in southern Lebanon, established in 1948 as a temporary refuge for exiled Palestinians. Today, the camp houses 70,000 people and is the hometown of generations. The filmmaker’s childhood memories are surprisingly warm and humorous, a testament to the resilience of the community. Yet his yearly visits reveal the increasing desperation of family and friends who remain trapped in psychological as well as political limbo.
