Which stage play was written by J.K. Rowling, Jack Thorne, and John Tiffany?

Harry Potter and the Cursed Child was written by J.K. Rowling, Jack Thorne, and John Tiffany.

The play opened in London’s West End in 2016. Jack Thorne wrote the script, while John Tiffany directed the production; Rowling developed the story with them. The narrative is set nineteen years after the events of the final Harry Potter novel and follows Harry’s son Albus Severus Potter.

Although published in book form, The Cursed Child is a stage play script rather than an eighth Harry Potter novel. Its theatrical format, live performances, and original cast distinguish it from Rowling’s seven prose novels. The published script was titled Harry Potter and the Cursed Child Parts One and Two.
