"Harry Potter and the Cursed Child" is a two-part stage play written by Jack Thorne, based on an original story by Thorne, J.K. Rowling, and John Tiffany. The play premiered in London's West End in 2016 and went on to have successful runs in New York and Melbourne.

The play is set nineteen years after the events of "Harry Potter and the Deathly Hallows," and follows Harry Potter, now a Ministry of Magic employee, and his youngest son Albus Severus Potter, who struggles with living in the shadow of his famous father. The play features a time-traveling plot that involves revisiting events from the original series, as well as introducing new characters and exploring the relationship between Harry and his son.

While the play received mixed reviews from critics and fans, it was generally well-received by audiences and won several awards, including nine Olivier Awards and six Tony Awards. It is important to note that the play is not a novel or a continuation of the Harry Potter book series, but a separate theatrical production with a different format and style.

There is currently no official announcement of a movie adaptation of "Harry Potter and the Cursed Child." While there have been rumors and speculation about a potential film adaptation, no official confirmation or plans have been announced by Warner Bros., J.K. Rowling, or any of the filmmakers involved in the previous Harry Potter movies.

It is worth noting that "Harry Potter and the Cursed Child" was written specifically as a stage play, and its format and structure may not translate well to a movie adaptation. Additionally, the story is considered by many fans as a continuation of the original Harry Potter series and would require a significant amount of backstory to be included for viewers who are not familiar with the books. However rumours still float around saying the original cast which since the particular story happens 19 years after brings the cast to be about the correct age to play their roles.

Ultimately, any decision to adapt "Harry Potter and the Cursed Child" into a movie would likely involve complex negotiations and creative decisions by the parties involved, and it remains to be seen if such a project will ever come to fruition.
