Antony Gormley on 'the magic' of sculpture

British sculptor Antony Gormley, creator of the Angel of the North, says sculpture has "a mystery and magic" in the way it triggers a response from the person looking at it.

Hardtalk's Stephen Sackur went to visit the artist's studio and see his work. Sir Antony told him: "Here is this still silent thing that encourages us to move and in moving our bodies to move our minds."
