'Antarctica has no government as such'

W. Herzog about filming Encounters at the End of the World

The film benefited greatly from the spirit of the Antarctic Treaty, which came into force in 1961 and which I consider to be one of the finest documents of the civilised world. It banned military activity on the continent and established the area as a scientific preserve, committing an entire landmass to the principles of peace and knowledge. There is also an unequivocal ban on nuclear testing or dumping of radioactive waste. The treaty is one of the most potent manifestations of civilised behaviour among nations in modern history. I remember a time when at least a dozen countries claimed segments of the continent as their national territory, but Antarctica has no government as such; it belongs to no one, and while making the film I was witness to the extraordinary international co-operation you find there.

The vast landscape of the continent is unique, but Encounters at the End of the World is more about the inhabitants of Antarctica than  anything else. There is a significant science being done there, which attracts a certain kind of person, and behind every door at McMurdo is an extraordinary character. With no indigenous population, no one there has anything in common other than a shared attraction to this immense, unspoilt and untouched area of the earth. Someone told me that everybody who isn't tied down falls to the bottom of the globe.
