DANNY Boyle, the artistic director of the opening ceremony for the London 2012 Olympics, has sent a hand-written letter to animal rights campaigners pledging that no harm will come to the animals used in the making of his show.

The Oscar winner wrote to Ingrid Newkirk, managing director of Peta, claiming "genuine care will be taken of the animals". It was prompted by fears over the welfare of the creatures in the £27 million curtain raiser at the Olympic Stadium on July 27.

Animals including 12 horses, three cows, two goats, 10 chickens, 10 ducks, nine geese, 70 sheep and three sheep dogs will appear in the opening scenes.

Mr Boyle, the award-winning director of Trainspotting and Slumdog Millionaire, also claims he will "vigorously" look at whether the creatures can be retired to an animal sanctuary after the ceremony.

The venue in Stratford, east London, is being mocked up to look like a meadow. The audience of about 62,000 and a billion people watching worldwide will see farmers tilling soil while animals graze.

Ms Newkirk wrote an to Mr Boyle in the hope he would accept that using live animals could trigger serious problems for the creatures such as stress and trauma.

Mr Boyle replied: "In our attempt to present an inclusive, rounded picture of British life I fear we will never see eye to eye.

"All I can say is that genuine care will be taken of the animals."

A Peta spokesman said: "Danny Boyle's reply does not fully address our concerns."
