Daniel Craig "cried" when he first heard Adele's Bond theme 'Skyfall'.

In an exclusive interview with Yahoo! Movies, the normally rugged star admitted that the first few notes of the pop sensation's ballad, made him very emotional.

"I cried," he said. "From the opening bars I knew immediately, then the voice kicked in and it was exactly what I'd wanted from the beginning. It just got better and better because it fitted the movie. In fact the more of the movie we made, the more it fitted it."

Director Sam Mendes also revealed that the singer had been sent an early copy of the script to help her compose the song, which she wrote with Paul Epworth.

"She came in very early before we started shooting and her main concern was 'I write songs about myself, how can I make a Bond song? My answer was 'just write a personal song'! Carly Simon's 'Nobody Does It Better' was a love song."

Adele's tune narrowly missed out on the number one spot, losing out to Swedish House Mafia's 'Don't You Worry Child'.

No 'Bond' song has ever reached top spot in the UK charts.
