Rowling has previously shut down suggestions of a big screen adaptation

Fans are speculating once again that a movie version of J.K. Rowling’s Harry Potter stage play could be on its way.

Intellectual property lawyer Brian Conroy has spotted that Warner Bros. Entertainment has applied for a trademark for Harry Potter And The Cursed Child in the UK, including copyright relating to “motion picture films”.

Though Rowling denied rumours of a Cursed Child movie earlier this year on Twitter, telling a fan they had “heard wrong”, it is possible she has changed her mind or that the play could be filmed “as live” for broadcast in cinemas or on TV.

Harry Potter And The Cursed Child, a two-part stage play co-written by Rowling, began previews at London’s Palace Theatre in early June. Set 19 years after the final Harry Potter novel, the stage show features new, older versions of Rowling’s famous characters Harry, Ron and Hermione.

Fans reportedly gave part one a standing ovation after its first performance, and reviews from Harry Potter aficionados so far have been overwhelmingly positive. A reviewer from The Telegraph wrote after seeing the play: “The audience came wanting magic and they got it in spades.”

Harry Potter And The Cursed Child will continue previewing until July 30, when it opens officially.
