One of the biggest secrets in London will finally be revealed Friday: what will happen at the opening ceremony for the Summer Olympic Games.
Friday night billons will finally get to see the extravaganza created by Danny Boyle, best known for the Oscar-winning film "Slumdog Millionare.
Few specifics have been released about the three-hour show. A big feat taking into account that thousands of performers and technicians are involved and there have been two dress rehearsals this week.
In fact, a twitter hashtag, #savethesurprise, has been started by Olympic organizers to help keep details private.
But some aspects of the show have leaked out.
The show's opening scene is dubbed "Green and Pleasant," after a line from poet William Blake's Jerusalem and will showcase an idyllic view of a British countryside.
The elaborate set will comprise rolling hills, fields and rivers, complete with picnicking families, sport being played on a village green and real farmyard animals.
Not many names of the celebrities that will be part of the ceremony have been released. But star footballer David Beckham has said he has a role in the spectacle.

Coverage on Local 4 begins at 7:30 p.m. with the tolling of the largest harmonically tuned bell in Europe, cast by the nearby Whitechapel Foundry.
Torch Travels up the Thames on last day
The Olympic torch will travel over water on its last day being carried on the royal barge Gloriana on the River Thames. The torch will then be the main attraction during the grand finale of the opening ceremony as it will be taken into Olympic Stadium and set the Olympic cauldron aflame, symbolizing the beginning of the Games.
On Thursday, it was taken past iconic London landmarks.
Crowds joined British Prime Minister David Cameron and his wife as the torch reached the doorstep of their Downing Street home. Next, the torch went past the Big Ben clock tower, carried by 81-year-old native Londoner Florence Rowe, who says she fondly remembers the excitement of the 1948 London Olympics.
The last major stop was Buckingham Palace, where Prince William, his wife Catherine, the Duchess of Cambridge, and Prince Harry greeted the torchbearers.
Men's football starts
Some Olympic competition commenced ahead of the opening ceremony.
Thursday saw the start of the men's football competition, with global favorites Spain and Brazil playing, though not against each other.
Spain, which won the European Championship this year and the last World Cup, suffered a surprising 1-0 defeat to Japan in one of eight games scheduled Thursday.
Brazil -- which, like Spain, is considered a likely contender to win Olympic gold -- beat Egypt 3-2. Great Britain, playing football in the Olympics for the first time since 1960, scored a 1-1 draw in its match against Senegal.
Two notable absences are Argentina and the United States, neither of which qualified.
U.S. lawmakers remember Munich killings
Sixteen members of the U.S. House of Representatives held a moment of silence Thursday to honor the 11 Israeli athletes killed at the 1972 Munich Olympics and urged Olympic leaders to hold a similar moment of silence at Friday's opening ceremony.
American Jewish leaders and the widow of one of the Israeli athletes have made a similar plea.
The International Olympic Committee says it will honor the slain athletes at a ceremony in September for the 40th anniversary, but so far there are no plans for an official remembrance Friday.
