(FILES) This file photo taken on April 3, 2014 shows China's best known and boldest contemporary artist, Ai Weiwei, posing in the garden of his studio in the suburbs of Beijing.
In the most tender moments of "Human Flow," Ai Weiwei's epic documentary on the worldwide migrant crisis, he is seen hugging, cooking with and cutting the hair of refugees. An ordinary filmmaker might be accused of getting too close to his subject but, as far as the Chinese dissident and internationally renowned artist is concerned, he is the subject.
