Warwick Davies is a cracking actor. The opening scene in the last 'Harry Potter' film, where he plays a captured Griphook, is mesmerising. His pacing is sublime, and the menace and regret he builds into the scene is fantastic.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
