When filmmaker Alison Klayman was shooting the documentary "Never Sorry" about Chinese artist and dissident Ai Weiwei, she was struck by the irony that Chinese authorities would go through the trouble to install surveillance cameras in the home a man who lives his life so openly on his blog and Twitter.
"I kind of felt that actually in some ways, the openness was almost a protection" she said. The best way to prevent the government from using his secrets against him, was to have no secrets.
Klayman was on hand at this year's Sundance film festival in Park City, Utah to debut her documentary, "Never Sorry". She spoke with Christiane Amanpour to discuss the film and what she's taken away from one of China's most influential artists and activists.
"He sort of has this mass appeal and ability to really engage all different kinds of audiences," she says, "whether they're sort of tech savvy or into design or architecture or art."
"I was really won over by how genuine his, sort of, believe in the individual, sort of, value of life, the dignity of life, how everyone in China and around the world deserves that, and I think that's really a big motivator for what he's doing."
