Daniel Radcliffe Worried About Harry Potter Return

Daniel Radcliffe was so worried about reports suggesting J.K. Rowling was planning a new book about the boy wizard, he wrote a letter to the author begging her to lock up her typewriter.

The young Brit has made it clear he no longer wants to don Potter's spectacles and invisibility cloak again after starring in eight films about the literary hero and his friends.

So when he heard Potter creator Rowling was planning another book in the series, he asked her for clarification.

Radcliffe tells Celebuzz.com, "I was worried! I texted her. I said, 'Look, is this true? Are you writing another book?'

"She wrote back that she was so pleased with my performance in Harry Potter 7 Part 1 that, as a reward, she promised to never write another book about Harry".

Currently appearing on Broadway in the musical How to Succeed in Business Without Really Trying, Radcliffe admits Harry Potter is far from his mind right now, but he's preparing for one last reminder before he's done with the boy wizard for good.

 He adds, "In a few months, I'll have to flip the switch and get back into Potter mode for a few days (to promote the final film), but right now there isn't time to be nostalgic about it".
