The 86-year-old monarch was shown in a pre-filmed sequence in which actor Daniel Craig, playing fictional British super-spy James Bond, arrived at Buckingham Palace in a taxi to escort the queen by helicopter to the ceremony.
Real helicopters then appeared over the Olympic Stadium during Friday's spectacular and parachutists playing Bond and the sovereign jumped out, just before Queen Elizabeth entered the stadium, wearing the same outfit.
It was one of the highlights of the show. Nicholas Brown, the British Broadcasting Corporation's director of drama production, said the sovereign gave a flawless performance.
“She got it in one take,” The Daily Telegraph newspaper quoted him as saying. “That’s what she does, and she does it very well.”
