In the 2002 film starring David Gulpilil called The Tracker we see many questions posed by the film, and answered by the viewer. Typical of a film I suppose but what isn’t typical are the powerful close-ups, overwhelming soundtrack, context and David Gulpilil.
Also on the DVD is a documentary of David Gulpilil by Gulpilil. The title is One Red Blood.
Gulpilil narrates and after being taken on a snapshot of his life he sums up that we are all brothers and sisters, with one red blood.
I dug that idea, despite leaving out some of the bloodless beings, because the concept uses color to unify rather than divide.
