Harry Potter author JK Rowling is to make three movies based on her Hogwarts spin-off, Fantastic Beasts and Where to Find Them.
Kevin Tsujihara, CEO at Warner Bros, told the New York Times last week that fans can expect a trilogy about "magizoologist" Newt Scamander after he persuaded the writer to adapt the book.
Published in 2001 and set in New York 70 years before Harry and co come onto the scene, the magical creatures guide was one of the school of witchcraft and wizardry's textbooks.
Rowling has described it as an "extension" of Potter's fantastical world.
"(Tsujihara and I) had one dinner, a follow-up telephone call, and then I got out the rough draft that I'd thought was doing to be an interesting bit of memorabilia for my kids and started rewriting," she said.
"I always said that I would only revisit the wizarding world if I had an idea that I was really excited about and this is it."

4/7 Harry Potter and the Order of the Phoenix
Acclaimed as the 'best film yet' by Rowling on it's release in 2007, The Order of the Phoenix grossed nearly $940m in total. In this scene Harry fights off a dementor after it attacks his cousin Dudley Dursley.
5/7 Harry Potter and the Half-Blood Prince
As the characters grew older, JK Rowling's narrative arc grew progressively darker with Harry facing evil forces more than ever.
6/7 Harry Potter and the Deathly Hallows
The final book of the seven-long series was turned into two epic-length films. Harry Potter and the Deathly Hallows marked a departure from Hogwarts and a traditional 'Potter' story arc.
7/7 Harry Potter and the Deathly Hallows
The final film, Harry Potter and the Deathly Hallows Part II, was softer in tone, with Harry, Ron and Hermione seeing their children off to Hogwarts.
The project was first announced in September 2013, with David Heyman (Harry Potter, Gravity) attached to produce. A director and cast have yet to be confirmed.
Rowling wrote Fantastic Beasts and Where to Find Them for Comic Relief between the publication of the fourth and fifth Harry Potter novels. Other spin-offs have included Quidditch Through the Ages and The Tales of Beedle the Bard.
Starring Daniel Radcliffe, Emma Watson and Rupert Grint, the Harry Potter films raked in an estimated £4.6 billion at the box office to become the highest-grossing film franchise in history.
