Video: Katie Couric Releases 45-Minute Daniel Radcliffe ('Harry Potter') Interview

Daniel Radcliffe doesn't have to be Harry Potter any more.

The star already finished with filming on "Harry Potter and the Deathly Hallow: Part 2" a while back, and is moving on to his next project: a role in a broadway musical, "How to Succeed in Business Without Really Trying."

Katie Couric asks him about the role (and much, much more) in a 45-minute interview she released as part of her webcast, @katiecouric. But it's the personal questions that Couric asks that are far more interesting.

For example, it turns out that Radcliffe is "an old man in a young man's shell" as he prefers staying home to the chaos ("Noise! Ridiculous, rubbish!") of bars and clubs.

"The last 'Potter' premiere, it was my ideal premiere, because I did the red carpet, went inside, introduced the film, went off," said Radcliffe. "I was at home by 10:30, with a bowl of Sugar Puffs, watching The History Channel. And I've never been happier! Rock 'n' roll!"

Radcliffe also sounds off about his childhood growing up on set, nude scenes on stage, and Googling himself. Check out the video for more!
