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...
