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...

With all the news concerning The Tales of Beedle the Bard there have been a few other things of note going on: - Alan Rickman, who plays Severus Snape in the Potter series appeared Wednesday night on Jimmy Kimmel Live. He also did an interview with SciFi.com where he discussed his filming schedule and the impact of the final film: "Well, it'll be a big finish, won't it? That's true, and appropriately. You can feel it now, the size of the undertaking." The online magazine also got a hold of producer David Heyman where he discussed the delay of the sixth film and the impact of the decision to split Deathly Hallows. - On Thursday, RDR Books officially withdrew its appeal of U.S. District Judge Patterson's decision to publish an unauthorized companion novel to the Potter series. J.K. Rowling's public relations agency issued the following statement: "We are delighted that this matter is finally and favorably resolved and that J.K. Rowling's rights -- and indeed the rights of all authors of creative works -- have been protected," the statement said. "We are also pleased to hear that rather than continue to litigate, RDR have themselves decided to publish a different book prepared with reference to Judge Patterson's decision." The Muskegon Chronicle goes on to say that in the new book the words "An Unauthorized Guide to Harry Potter Fiction and Related Materials" appears boldly below "The Lexicon" title and above author Steve Vander Ark's name. There is further explanation that neither Rowling nor a host of others with trademarks and other interests in the Harry Potter series had any part in the book. - Finally, USA Today has written up a preview of ABC Family's Potter weekend which begins tonight at 7:30 p.m. ET. You can expect to see deleted scenes from Goblet of Fire as well as a look into Half-Blood Prince. The paper quotes producer David Heyman on the sixth film: "It's different than the other films. It's not the non-stop action that some of the others are, although there is some action. It's more of an emotional film."

The attorney for JK Rowling during her case against RDR Books will be speaking at Harvard University this Thursday (November 6th) at 12:15. The discussion about the case will run for 45 minutes in Pound 201. Thanks to Christina for the tip!

The Detroit Free Press is reporting this morning that a notice of appeal will be filed by attorneys on behalf of Roger Rapoport and Steve Vander Ark in an attempt at "preserving the men's right to continue the legal battle for their Harry Potter book." As reported last week, Judge Patterson ruled in favor of J.K. Rowling and Warner Brothers stating that The Lexicon takes too much from Rowling's work. Rapoport and Vander Ark are looking into editing the current edition of the book. No statement has been issued by either J.K. Rowling or Warner Brothers at this time.

The Grand Rapids Press has spoken with the author of The Harry Potter Lexicon, which just yesterday had its publication halted by a New York City judge. Vander Ark's thoughts after hearing the verdict: "I've always been a fan of Harry Potter and of Rowling and my hope all along was that we'd find an amicable way to settle this. I'm disappointed, but this is the way it went and I don't hold any ill will at all. It was a question of law over a difference of opinion and, in a way, I'm glad that it's finally over." The newspaper notes that Vander Ark is currently in England where he's working on a new book which visits real-life locations placed in the Potter series.

After this morning's JKR VS RDR verdict in New York City, we received official statements from Warner Brothers and JK Rowling. Now, we have a statement from RDR Books, who was to be the publisher of the Harry Potter Lexicon: "We are encouraged by the fact the Court recognized that as a general matter authors do not have the right to stop the publication of reference guides and companion books about literary works. As for the Lexicon, we are obviously disappointed with the result, and RDR is considering all of its options." The full text of the trial decision is also now online. It notes that RDR has to pay statutory damages of $750 for each of the seven Potter books as well as Fantastic Beasts and Quidditch Through the Ages. That brings it to a total of $6,750.
