Alan Yentob returns to burble over another litany of cultural endeavours. Tonight he meets architect, photographer, curator and blogger, Ai Weiwei, the politically outspoken Chinese artist behind the Tate Modern installation Sunflower Seeds, which is made up of millions of hand-crafted porcelain seed husks, and grabbed headlines when it was unveiled on October 12, 2010. The presenter reveals how Ai's provocative works have helped forge his reputation in creative circles, but he remained relatively unknown in the UK until he was commissioned by one of the nation's most celebrated contemporary exhibition spaces. Stay tuned to BBC1 for slightly more low brow viewing at 00.25am; they're only airing Drop Dead Gorgeous.
