Anderson Cooper, Daniel Radcliffe Talk About Broadway (VIDEO)

Anderson Cooper has been in the studio recording his narration for the upcoming revival of the Broadway musical "How To Succeed In Business Without Really Trying." The show's producers made a short video featuring Cooper and Daniel Radcliffe, who is starring in the show.

"I never expected to do something like this," Cooper said in the video, adding that he jumped at the opportunity.

"I'm a big fan of Daniel's, so I said, 'why not?'" he said.

For his part, Radcliffe said that he had long noticed a "playful glint" behind Cooper's eyes that made him want Cooper to narrate the show. Also, he noted, the man who narrated the last revival of the show was Walter Cronkite.
