Australia picks first Aboriginal-language movie as Oscars entry
The movie, which was filmed entirely in the indigenous language of Ganalbingu, was screened at the Cannes film festival in May, winning de Heer a special jury prize.
Starring Jamie Gulpilil, Richard Birrinbirrin and Frances Djulibing, it tells a fictional story set in the distant past in which the lead character is attracted to one of the wives of his older brother.
In order to teach his brother tribal law, the older sibling tells a mythical story of love, kidnapping, sorcery and revenge.
Neat.
There’s just one (!) hit for “Ganalbingu” in Wikipedia, here you go:
The linguistic variety is echoed by the cultural diversity in the area, evidenced by the number of different religious ceremonies and the multitude of artistic forms in design, music and dance. People speak Ndjébbana, eastern Kunwinjku, Kune, Rembarrnga, Dangbon/Dalabon, Nakkara, Gurrgoni, Djinang, Wurlaki, Ganalbingu, Gupapuyngu, Kunbarlang, Gun-nartpa, Burarra, and English. Most people have command of at least three of these languages.
That’s from the article about the Maningrida indigenous community. (You can see where it is in Google Maps.)
