Daniel Craig and the cast of the new James Bond adventure 'Quantum of Solace' braved the brisk London air for the film's Royal world premiere Wednesday night -- and ET was there! But it was two high-profile young men, not Bond, who stole the spotlight…

"It's a real honor to have them here tonight, for a particularly good cause," says Craig of special guests of honor Prince William and Prince Harry.

The Royal family traditionally attends the world premiere of every Bond movie, and this year was no exception: The two princes walked the red carpet at the Odeon West End in Leicester Square to screams of delight. At the request of William and Harry, the screening benefited their Royal Highnesses' chosen charities, Help for Heroes and The Royal British Legion.

"This seems to be bigger than the last time," says Craig of the Royal premiere, responding when asked how many more Bond film's he'd do, "I don't know, I can't tell -- let's get this evening out of the way and we'll figure it out."

In theaters November 14, 'Quantum of Solace' finds 007 out for revenge on a mission that takes him to Austria, Italy and South America. Out to uncover the organization that blackmailed Vesper (in 'Casino Royale'), Bond soon discovers his enemies are more dangerous and far-reaching than anyone could have imagined.
