It would be difficult to say of the two who is more famous: Bono or George Clooney.

And earlier this week, the two men sat down for some chat, when the U2 front man interviewed Clooney, who was being honored by Time Magazine as one of the world’s most influential men.

CNN was on hand to shoot the interview, which was shown on Anderson Cooper.

In a profile of Clooney written by Bono for Time, he described him as “a new kind of American radical”… a post-’60s, post-obvious, post-postmodern radical, not the left-leaning Hollywood bleeding-heart do-gooder that many think.” 

“He believes that his country is a contagious idea that should be embraced by the world — but not by force, and not out of fear,” Bono said of his friend.
