He's 21 and a world-famous movie star, but Daniel Radcliffe's idea of a perfect night is sitting at home with a bowl of Sugar Puffs, watching The History Channel.
In an interview with CBS Evening News anchor Katie Couric, to be broadcast this week on "Sunday Morning," the "Harry Potter" actor admits, "This is the joke about me that people have on set, is that I'm an old man in a young man's shell."
He says he avoids clubs and parties -"It's horrible. It's just horrendous. Noise. Ridiculous, rubbish."
He also says he avoids Twitter: "I think Twitter is a really strange thing, because there are certain people in the world who are naturally epigrammatic, and can say things very concisely, and very brilliantly, in natural space and time. But I think they are a very small number of people."
Radcliffe is set to open on Broadway March 27 in the 50th anniversary revival of "How to Succeed in Business Without Really Trying," in which he stars as corporate ladder-climber J. Pierrepont Finch.
It is his second Broadway show. In 2007 he took on his first stage role in the West End play "Equus" and brought it to Broadway the following year. He earned worldwide praise for it but he never read a review. And he won't read reviews - even good ones - for "How To Succeed."
"If you're going to read the good ones, you have to read the bad ones," he explains to Couri , who first interviewed him in 2001 as the first "Harry Potter" movie was about to open. "And I certainly don't want to read the bad ones."
In his first television interview about this new role, Radcliffe gave Couric a tour of the musical's set, and discussed everything from leaving the Harry Potter "family" to his involvement in The Trevor Project, an advocacy group for gay and lesbian teens. This interview will be broadcast on "Sunday Morning" on March 13 at 9 a.m. ET.
Couric and Radcliffe's extended conversation can be seen on @katiecouric, Couric's weekly webshow beginning Sunday, March 13, after 9:30 a.m. ET.
