Ai Weiwei: Never Sorry director 'shocked' by artist
A new documentary by New York-based journalist Alison Klayman on Chinese dissident and artist Ai Weiwei is set to hit screens.
Ai Weiwei: Never Sorry follows the artist's work and appeal against a 15m yuan ($2.4m, £1.5m) fine for tax evasion.
In June, a group of TV executives from Chinese television boycotted a Sheffield film festival over the screening of the film.
