     The theme of the London Olympics opening ceremony will be "Isles of wonder", organizers revealed

on Friday. The title came from an amazing speech about the beauty of the island in Shakespeare's play.

     Oscar-wining filmmaker Danny Boyle, the ceremony's artistic director, said the theme was inspired by

a passage from William Shakespeare's comedy The tempest.

     Boyle, whose Slumdog Millionaire won eight Oscars, said he was trying to keep the details of the

July 27 ceremony under wraps, but he gave away the first details of the event, set to be watched by one

billion TV viewers.

     Boyle said that he had had the biggest ringing bell made in Europe, which will hang at one end of the

Olympic Stadium and be rung to start the opening ceremony. Boyle told BBC that he wanted people to

hear it for hundreds of years.

     Fellow film director Stephen Daldry, the creative director for the London Olympics opening

ceremony, told reporters the opening show would project a journey which will celebrate who we are ,

who we were and who we wish to be.

     However, Boyle admitted that London would not rival (与……匹敌) the breathtaking opening

ceremony staged at the Beijing Olympics four years ago, due to the tougher economic times.

     It was announced the ceremony in December that the budget for the opening and closing ceremonies

had been doubled to 81 million pounds.

     Boyle also promised that the ceremony would be more intimate(个人的) than the splendid

performance of drummers and dancers in Beijing's Bird's Nest stadium.

     Boyle also promised that the show would be armed with a British sense of humor.
