Author J.K. Rowling confirmed this week that the film adaptation of her book "Fantastic Beasts and Where to Find Them" would become a trilogy of movies. The famed creator of the "Harry Potter" series put to rest rumors about a film adaptation of her recent play "Harry Potter and the Cursed Child," saying there were no plans to make it into a movie.

"You heard wrong, I'm afraid. #CursedChild is a play. #FantasticBeasts will be 3 movies, though!" Rowling wrote in a tweet to a fan from her verified Twitter account Monday.

Rowling has continued to write novels following the end of the "Harry Potter" series and the final release of its film adaptations in 2011. She has penned several books in the years following, such as “The Casual Vacancy” which was released to mixed reviews.

"Harry Potter and the Cursed Child" is set to open as a West End play, written in collaboration with Jack Thorne and John Tiffany, slated for its first performance at London’s Palace Theatre July 30. The play follows Harry Potter 19 years after the end of the last book in the series, when Potter is now father to a son named Albus, a young boy who struggles to come of age in the shadow of his family legacy.

As past and present fuse ominously, both father and son learn the uncomfortable truth: Sometimes darkness comes from unexpected places,” read a press release for the play, the Wall Street Journal reported in February.

"Fantastic Beasts" features creatures from the Harry Potter books, and Rowling wrote its film adaptation. Slated for release in November 2016, the film features Eddie Redmayne, Ezra Miller, Ron Perlman and Colin Farrell.

The adventures of writer Newt Scamander in New York's secret community of witches and wizards 70 years before Harry Potter reads his book in school,” reads a description for the film from the Internet Movie Database. Scamander will be played by Redmayne.
