Oscar nominated Virunga film enjoys Hollywood publicity

The documentary movie Virunga, backed by Leonardo de Caprio, hopes its Oscar nomination will help the campaign to protect one of Africa's oldest national parks. Virunga, which is in the Democratic Republic of Congo, is at risk from oil exploration and conflict. Prince Emmanuel de Morode, the director of Virunga, has been telling the BBC's Russell Padmore about his role in the film and the park's natural beauty.
