He filmed Comboio de Canhoca (The Train of Cahoca) in 1989, though for political reasons the film was not released until 2004. In the film, based on a real-life colonial atrocity in the 1950s, Portuguese secret police arrest 59 Angolans, placing them in a train boxcar which is left on a rail siding for three days.[2] As the heat increases, the solidarity of the prisoners break down and they suffer asphyxiation.[3]
