The Olympic Stadium will be transformed into the "British countryside" for the opening ceremony of the London 2012 Games on 27 July.

A cast of 10,000 volunteers will help recreate country scenes, against a backdrop featuring farmyard animals and landmarks like Glastonbury Tor.

The opening scene of the £27m ceremony will be called "Green and Pleasant", artistic director Danny Boyle revealed.

The BBC's Arts Editor Will Gompertz takes a closer look.
