London 2012 Olympics: Muhammad Ali and Aung San Suu Kyi considered for opening ceremony Debate in the UK has mostly focused on the relative merits of British candidates for one of the great honours of the Games, with Sir Steve Redgrave and Roger Bannister featuring high on many lists. Both are thought to have signed confidentiality agreements with the London Organising Committee of the Olympic Games, suggesting they might have a role in the closing moments of the ceremony. As well as Redgrave and Bannister, Daley Thompson, a hugely popular figure and close friend of Coe's, has been discussed. So too have Dames Kelly Holmes and Mary Peters. Discussions are also continuing about David Beckham's involvement now that he has been left out of the football squad. London's consistent theme of using the Games to "Inspire a Generation" means organisers will also consider leaving the final honour to a young person, a "golden child" who represents the target audience. The final decision will be made by a Locog subcommittee comprising Boyle, head of ceremonies and fellow Oscar-winner Stephen Daldry, 2012 chairman Lord Coe and chief executive Paul Deighton, and head of communications Jackie Brock-Doyle. Such is the sensitivity around the ceremony that government might try to seek sign-off, although culture secretary Jeremy Hunt told The Daily Telegraph that he did not know and had not asked who would be involved. Some or all of the candidates could feature in the final stages of the torch's journey into the Olympic Stadium. The possibility of multiple lighters cannot be ruled out. A key part of the closing ceremony is thought to be the lighting of the five Olympic rings, a device that would allow more than one candidate to play a part were the five lit rings to converge into a single flame. The final location of the cauldron is also still unknown, but there are suggestions that it might be movable, capable of being transferred from outside the stadium to the heart of the arena. Whatever the final decision it is unlikely to be formulaic or predictable. Boyle has already impressed with the originality of his thinking. The ceremony seems almost certain to have a mildly political undercurrent, with elements celebrating the public servants of the NHS and the national history of protest. Both Boyle and Daldry have made massively popular films with strong political and social messages. The opening ceremony promises to reflect that approach, rather than be a parade of tourist cliches. "This will be more Grimethorpe Colliery Band than the Coldstream Guards," as a source put it.
