Movie Blog: 'Ai Weiwei: The Fake Case' Review In April 2011, Ai Weiwei -- the Chinese artist who helped design the Beijing “bird’s nest” Olympic stadium and who filled London’s Tate Modern with 8 million sunflower seeds -- was arrested by authorities in his home country. They held him in detention for nearly three months on what later turned out to be tax fraud charges. After that, they placed their most prominent international artist on house arrest.
