Line-up for Encounters South African International Documentary Festival announced

The Oscar- and BAFTA-nominated Virunga is an eco-thriller set in the DRC's national park, a World Heritage Site that is home to the world's last mountain gorillas. Only two days before the film's premiere, park warden Emmanuel de Merode was gunned down after delivered damning evidence that Virunga is in grave danger. With the Congo's fragile peace crumbling, the park and its gorillas are under threat not just from the rebel army, but also from a corrupt mining company that has found oil there.

Winner of Best Documentary at Tribeca, Democrats follows Paul Mangwana of ZANU-PF and Douglas Mwonzora of the opposition MDC-T, as they consult Zimbabweans across the country as part of leading the process of drafting a new constitution. With tension crackling between Mangwana's joker and Mwonzora's straight guy, these two unlikeliest of collaborators must cling together if they're to weather what is about to be a massive political storm.

That Sugar Film

That Sugar Film is a funny and frightening look at what protagonist Damon Gameau believes is the greatest danger to his young family's healthy future: sugar. Swearing to a two-month diet of only hidden sugars - those secreted in supposedly 'healthy' foods - Gameau assembles a crack team to monitor the effect on his body and mind. With cameos from Stephen Fry and Hugh Jackman, this entertaining film is sure to spark the most dietary debates since Tim Noakes first used the term 'banting'.

Encounters will also host the world premiere of Jazz Heart, festival favourite Steve Kwena Mokwena's moving documentary about reconnecting with his father, jazz musician Andrew 'Bra Pat' Mokwena.

Three biopics on remarkable Africans have also been added to the line-up:

• Adriaan De La Rey and JP Kotzé's In Search Of Our Own: The Forgotten Legacy of Norman Eaton remembers the pioneering South African architect who designed houses for the likes of Pierneef and Alexis Preller;
  
• Lebogang Rasethaba's Prisoner 467/64: The Untold Legacy of Andrew Mlangeni profiles one of South Africa's unsung heroes, the 11th accused in the Rivonia Trial; and
  
• Asni: Courage, Passion and Glamour in Ethiopia celebrates jazz diva Asnaketch Worku, Ethiopia's Edith Piaf of the 1950s and 60s, a time when men were still playing female roles in theatre productions there. She was famed for her trailing dresses and swaying hips, notorious for her many lovers, and infamous for daring to sing the lyrics: "Why should I have my own husband, when I can share yours?"
