Fans of the Harry Potter franchise have been buzzing about the upcoming prequel film “Fantastic Beasts and Where To Find Them.” J.K. Rowling published “Beasts,” a fictional textbook from Hogwarts School of Witchcraft and Wizardry, back in 2001.

The so-called “textbook” contains information about different magical animals with notes “hand-written” by Harry Potter, Ron Weasley and Hermione Granger, according to The Examiner.

News of a film adaptation has set Potterheads off into a frenzy of excitement. In an interview with Entertainment Weekly, actor Daniel Radcliffe expressed his anticipation and enthusiasm toward the project.

“I can barely keep myself in this chair! I am very excited, but I’ve also been asked about it a lot, and I don’t have any information to give, unfortunately,” Radcliffe said.

The film will not solely focus on the book’s protagonist Newt Scamander, an expert in magical creatures, but on four heroes who must work together. The film will be released in November 2016 and will be the first of a trilogy, with sequels planned for release in 2018 and 2020.

Fans were already excited about Rowling’s announcement from earlier this year that a play titled “Harry Potter and the Cursed Child” was in the works. The play would be a continuation of the seven-book series, set in the same time as the epilogue of the last book.

Albus Severus, one of Harry and Ginny’s children, and Harry will be the main focus of the play, according to Rowling. The play will premiere on July 30, 2016 at the Palace Theatre in London just a few months before the premiere of Fantastic Beasts.
