How will it all come together?
The ceremony's mastermind, filmmaker Boyle, has stressed that the 3-hour show will take viewers on a sweeping journey through Britain's history, one that captures the nation's identity, values, heritage, as well as its present and future. In their own ways, each of the elements represents some aspect of Englishness - though some in quirkier ways than others.
Seventy sheep are set to star in the ceremony, alongside 12 horses, 10 chickens and three sheep dogs. Britain may no longer be the farm-based economy it used to be, but no less than 50,000 sheep farms still dot the nation's fields - the largest sheep flock in the 27-nation European Union. But the animals have been chosen for a far more symbolic reason: Shepherds and the pastoral life have long been romanticized by British writers like Edmund Spenser, and at every patriotic event Britons belt out the glories of "England's pleasant pastures" to William Blake's anthem "Jerusalem."
Animal rights activists are none too pleased that farm animals have been roped in to perform, however. The group Viva! has complained that the show "smacks of the Roman gladiatorial arena.
Each of Great Britain's four nations - England, Wales, Scotland and Northern Ireland - will be represented by a maypole topped with their national flowers. A pagan folk symbol, the maypole is still commonly erected in British villages during May Day celebrations (as well as elsewhere in Europe) to celebrate the return of warmer weather.
"It's an essential part of rural life," said Peter Halfpenney, the "squire" - or president - of a Morris dancing group. He was delighted that Boyle chose to feature maypoles but disappointed that Morris dancers - often ridiculed for their folksy costumes - don't get to take part.
Is there a sport more English than cricket? Played and followed avidly in Commonwealth countries like New Zealand, South Africa and India, the sport's many technical rules - and the lack of fast, exciting action - baffle almost everyone else. Fans love the "gentleman's sport" for the strategy and patience it requires.
Boyle has disclosed there will be a dance number of nurses celebrating the National Health Service, the country's universal health program. Not only that: performers were recruited from the NHS. Why? To Britons, nurses are the tough, strong and matronly face of the NHS, a nationally cherished post-war institution.
BOND, JAMES BOND
Fast cars, fast women, Martinis shaken not stirred: The super spy 007 needs little introduction. First introduced by writer Ian Fleming in 1953, the fictional British secret agent is the protagonist in the longest-running film franchise to date, with Craig the latest incarnation in a long line. The Bond character's dress, cars and expensive tastes ooze British sophistication.
Wellies, flooded campgrounds, no showers for days - the Glastonbury music festival is a summer rite of passage for many Britons. Started by farmer Michael Eavis in 1970 the day after Jimi Hendrix died, it has taken place every year since then in Somerset. Rain, hippies, music and mud - sounds like a recipe for an open-air Boyle extravaganza. Celebrities at the opening ceremonies
There will be monarchs, presidents, prime ministers and David Beckham. Friday's opening ceremony for the London Olympics is an A-list affair.
Among the 60,000 spectators at Olympic Stadium will be Queen Elizabeth II who as British head of state will officially open the games along with royals including Prince William and his wife Kate, and Prince Harry.
There's sure to be a sprinkling of showbiz royalty, too, with Brad Pitt and Angelina Jolie, recently filming in Britain, the most often-cited names.
The British government says more than 80 heads of state and government will be in the audience, including royalty from Brunei, Luxembourg, the Netherlands, Spain and Sweden.
The U.S. will be represented by first lady Michelle Obama and Republican presidential hopeful Mitt Romney will also attend.
Beckham, who helped bring the games to London and is widely rumored to have a role in the ceremony, will be there, and British newspapers have speculated that boxing great Muhammad Ali may also be involved.
