'Wolfram' Bunya Productions A decade after his outback Western Sweet Country, First Nations director Warwick Thornton returns, with his new film, Wolfram, to the colonial frontier of 1930s Australia. Like Sweet Country, Wolfram is set in Thornton's hometown of Alice Springs, and inspired by real family history, that of Thornton's and David Tranter, co-screenwriter (with Steven McGregor) on both films. Sweet Country traced the story of Tranter's great-grandfather, one of the many Aboriginal men taken from their families to provide free labor for white ranchers.
