From the Guardian:
Harry Potter is set for the West End with JK Rowling collaborating on a stage play about the young wizard's life before his arrival at Hogwarts.
Rowling, author of the seven-volume best-selling Harry Potter series, will be a co-producer and collaborate with a writer on the play, which it is hoped will hit the stage in 2015.
In a statement, Rowling said: "Over the years I have received countless approaches about turning Harry Potter into a theatrical production, but Sonia [Friedman] and Colin [Callender]'s vision was the only one that really made sense to me, and which had the sensitivity, intensity and intimacy I thought appropriate for bringing Harry's story to the stage.
London and New York producers Callender and Friedman said the play would tell "the previously untold story of Harry Potter's early years as an orphan and outcast".
Wow. If it'd just been an adaptation of the first book, I wouldn't have been particularly surprised (or all that excited, honestly), but this is INTERESTING.
