Dan Radcliffe apologized to Robbie Coltrane for Phone Prank

Daniel Radcliffe’s tendency to prank his fellow Harry Potter cast-mates often added levity to the set, but there was at least one time when his antics went a little too far.

Reportedly, Robbie Coltrane, who portrayed Hagrid in the films, was once a victim of a prank where the young actor changed the settings on his friend’s phone from English to Turkish. The joke seems harmless enough—except that Coltrane was left unable to make calls!

The infuriated actor had a hard time finding anyone on set who could change the settings of his phone back to English, and Radcliffe was left feeling understandably sheepish about what he had done. Coltrane remembers the event clearly:

Eventually we found a girl in the Harry Potter make-up department who was Turkish Cypriot. She phoned her mum and was chatting away in great detail until they sorted it out. I think Daniel was so upset at what had happened that he wrote me that note...'Dear Mr. Coltrane, I'm sorry I changed your mobile telephone into Turkish...

J.K. Rowling to appear on 'The Daily Show with Jon Stewart' tonight at 11:00 EDT

As part of her New York City tour promoting the release of her new book, The Casual Vacancy, JK Rowling today visited comedian Jon Stewart on his Comedy Central program, "The Daily Show." Stewart is a long-time fan of Rowling and the Harry Potter books; the above photo captures Stewart in Honeydukes when he visited the Wizarding World of Harry Potter last year with his family.

Considering both Rowling and Stewart touch on political satire in their writing, and that those themes are especially present in Casual Vacancy, we at MuggleNet anticipate this will be a very interesting interview.

The program will air tonight at 11:00 EDT. MuggleNet will post a video of the interview as soon as it's available, and let you know beforehand if any Potter-related info is revealed.
