Hollow City [Na Cidade Vazia] (2004, dir. Maria Joao Ganga)

A displaced orphan escapes into the city: he wants to go home. An Angolan version of Oliver Twist after a fashion, set in the early 1990s in the context of civil war. Offers a ground-level perspective, though struggles at times to balance narrative with didactic elements. Impressive, nevertheless, and worth investigating.

No trailer online, though a subtitled version of the film is here
