Decades of scientific exploration have revealed that some regions of the Earth may be similar to the geological environments observed on the surface of Mars. Australia's central desert shares certain unique and singular characteristics with the "red planet": extinct volcanoes, traces of asteroid impact, minerals, arid valleys, sandstone and stony soils the colour of blood caused by the same weathering process. Arthur and Corinne Cantrill's film At Uluru encapsulates the essence of these environments and introduces us to the heart of this continent: the great rock Uluru. Instead of the rolling, wooded landscapes of the coastal areas, At Uluru took the Cantrills to the unfamiliar landscape of Central Australia and its great rock formations that rise up out of the reddened, flat desert. These great rocks are awe-inspiring in their magnificence and are forever changing due to the light and weather conditions.
