Matthew Sweet talks to one of Britain's greatest living sculptors, Anthony Caro. He moved away from his mentor Henry Moore's figurative style of sculpture to begin working in steel over 50 years ago. Now 86, Anthony Caro talks to Matthew about his new series of 40 works, and the pleasure of discovering the uses of the forklift truck as an octogenarian. And as the 21st sculpture festival in London takes place this week, Night Waves explores the challenges facing sculpture in the next decades. Is there a recognisably 21st century sculpture, and as more art becomes three dimensional, how can sculpture define itself? Susannah Clapp reviews the first stage play by the best-selling author of 'The Curious Incident of the Dog in the Night-Time', Mark Haddon And Matthew Sweet talks to David Baddiel about his new film, The Infidel, where a Muslim taxi-driver discovers he was adopted as a baby and his birth parents were Jewish. Can comedy challenge religious prejudice or does it risk reinforcing stereotypes?
