After hearing rumours of another book, Radcliffe reportedly texted author J.K. Rowling, asking for clarification of whether this was true. Radcliffe says she wrote him back saying she was so pleased with his performance in HARRY POTTER AND THE DEATHLY HALLOWS: PART 1 that she promised him she would not write another Potter book.
During his talk with Celebuzz.com, Radcliffe also added that he’ll be back in Potter mode in a few months to promote the film, but is excited to be done with the project. We feel for you, Radcliffe, you're just ducking out while you're still ahead. Much love and respect!
