Ai Wewei: Never SorryAirs Monday, February 25 at 9:00 PM Named by "ArtReview as the most powerful artist in the world, Ai Weiwei is China's most celebrated contemporary artist, and its most outspoken domestic critic. In April 2011, when Ai disappeared into police custody for three months, he quickly became China's most famous missing person, having first risen to international prominence in 2008 after helping design Beijing's iconic Bird's Nest Olympic Stadium -- and then publicly denouncing the Games as party propaganda. Since then, Ai Weiwei's critiques of China's repressive regime have ranged from playful photographs of his raised middle finger in front of Tiananmen Square to searing memorials to the more than 5,000 schoolchildren who died in shoddy government construction in the 2008 Sichuan earthquake. Against a backdrop of strict censorship, Ai has become a kind of Internet champion, using his blog and Twitter stream to organize, inform, and inspire his followers, becoming an underground hero to millions of Chinese citizens. Ai Weiwei: Never Sorry , premieres on the award-winning series Independent Lens , hosted by Stanley Tucci.
