James Bond actor Daniel Craig said that he was so taken by Adele's 'Skyfall' theme song that he cried when he first heard it.

Adele had been long rumoured to perform the tune for the forthcoming James Bond flick Skyfall but her participation was only confirmed recently.

The track was released to widespread acclaim and the theme song was noted for its classic 007 sound.

Craig - who is due to play James Bond for the third time in Skyfall - told Yahoo that he became emotional listening to the track and knew that it was the perfect Bond song. He said:

"I cried. From the opening bars I knew immediately, then the voice kicked in and it was exactly what I'd wanted from the beginning."

Craig continued: "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."
