This sounds like it could be a really interesting movie. I'm sold on the synopsis alone but I couldn't find much else about it online, like a trailer, or some clips.
Titled Children's Republic (La république des enfants) by Bissau-Guinean filmmaker Flora Gomes, the synopsis for the film follows:
In West Africa, there's a small country every adult abandoned. The children get organized and the Children's Republic becomes a stable and prosperous country. But the children can no longer grow up.
Researching, I found very few links which made it difficult to put a comprehensive post on the film together. But I learned that it's a futuristic tale of a city ruled by children, its only inhabitants after a horrific and tragic civil war. And even more strange, the children, for some reason, don't age. Conflict arises when child soldiers from the outside enter this unusual community of children who don't age. It's been suggested by some that the film is an allegory on the possibility of African youth taking over the hope of building democracy on the African continent without forgetting its past.
There's a website set up for the film but it's all in French. I used Google to translate and what I typed above is what I could piece together based on the not-very-good translation.
The film was produced in France (I found 2 different production dates on different sites. Some say it was produced in 2010, while others say in 2012) with funds from the European Union, and it's categorized as a fantasy film.
Danny Glover co-stars in the film, which is set in Guinea-Bissau, in West Africa, along with Melanie Vales Rafael, and Hedviges Mamudo.
Director Flora Gomes (who's from Guinea-Bissau) studied film at the ICAIC in Cuba. His directing resume includes films like Mortu Nega (1987), which screened the next year at the Venice International Film Festival. After That, he directed The Blue Eyes of Yonta (1992) and Po di Sangui which screened at the Cannes Film Festival in 1996.
Children's Republic is his 7th full-length film.
There's sadly no trailer for it. I couldn't find one in any language. But there are lots of on-set photos and pics from the film around the web, like the one above with Glover.
It's scheduled to screen at the twenty third (23rd) edition of the Pan-African Film & TV Festival of Ouagadougou (FESPACO), which will take place from February 23 to March 2, 2013.
