The Aborigine boy is portrayed by David Gulpilli and at the time of filming the film could not speak English. He lives in a different culture and world where he is percieved as a man. He lives off the fruits, animals and finds water in the land. The White girl is portrayed by Jenny Agutter and the White Boy is portrayed by Roeg's son Luc Roeg. After their father sets their car on fire and then shoots himself, the girl takes it upon herself to lead her and the boy for help. They're trapped in the desert and have no survival skills whatsoever. Luckily the Aborigine knows what to do and he shares his food and water with the two.
This is a contrast story of two very different cultures and Roeg edits scenes in a way to compare and contrast different ideas and cultures.
The Aborigine and the girl have complicated feelings for one another. The girl on the one hand wants to return home, but on the other she doesn't seem to truly trust him or understand his ways. Her younger brother is able to communicate with him through sign language and other means. The Aborigine starts to develop sexual feelings for the girl and he hopes to fornicate and perhaps that's why he never truly leads them to help.
Nicholas Roeg was both cinematographer and director for the film. The film has beautiful compositions and beautiful landscapes full of animals from the Outback.
And with the assistance of a young Aboriginal boy in the middle of his "walkabout" -- the siblings journey through adversity and mystery toward their own adulthood.
Along the way cultural differences cause confusion and alarm. It is a film about survival thanks to human kindness. But more than anything it is a startling view of how racism and cultural differences are so engrained, no amount of human kindness can make them go away.
A beautiful and tragic experimental film about both the strengths and flaws of the human condition.
