Despite rumours that David Beckham wasn’t actually driving the speedboat — named Max Power — that sped him down the Thames, organisers insist he was operating the controls, with other crew members on hand just for safety (though they admit he didn’t dock the boat himself). Apart from close-up shots of Becks, the entire trip was filmed live, overseen by Billy Elliot director Stephen Daldry.

Stuntman Gary Connery dressed as the Queen to leap from a helicopter 550ft above the stadium. Mark Sutton, a former soldier, jumped as 007. They had taken off from Stapleford Airfield in Essex and hovered over London for 30 minutes before the jump — then landed outside the stadium, next to Anish Kapoor’s steel tower.

The 75 ‘dove bikes’, 70 ridden by volunteers found on internet cycling forums, rehearsed in secrecy. The fabric wings had tiny LED lights and were operated by aluminium rods attached to the handlebars which riders pressed to create the flapping effect. Bob Haro, who created the flying bike scene in ET, choreographed the sequence.
