A play based on J.K. Rowling’s Harry Potter tales will open in the West End within two years.

Rowling will not write the stage piece — however, she will co-produce and collaborate with a playwright.

Rowling’s seven-volume Harry Potter series began with The Philosopher’s Stone, published in 1997.

All told the books have sold well in excess of 450 million copies and been translated into 77 languages.

Eight movies were made featuring Daniel Radcliffe as the boy wizard with the thunderbolt scar on his forehead, and Rupert Grint and Emma Watson, as Ron Weasley and Hermione Granger, his best pals at Hogwarts School of Witchcraft and Wizardry.

But the play, to be steered by prominent London and New York producers Sonia Friedman and Colin Callender, will mine ‘the previously untold story of Harry Potter’s early years as an orphan and outcast’.

Harry Potter’s theatrical adaptation will seek to ‘offer a unique insight into the heart and mind of the now legendary young wizard. A seemingly ordinary boy, but one for whom destiny has plans...’

Rowling noted the numerous approaches she has received about putting Harry Potter on the stage, but the vision put forth by Sonia and Colin ‘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.

A theatre has yet to be negotiated, but with a show of this quality — almost a licence to print money if all involved get it right — hopefully the right spell will deliver a theatre exactly when the show’s ready to go in 2015.
