JK Rowling has already started writing the third Harry Potter prequel movie

Fantastic Beasts: The Crimes of Grindelwald isn’t even out in cinemas yet, but JK Rowling is already hard at work on the follow-up.

The second in a planned five-film prequel franchise exploring the Wizarding World of Harry Potter arrives in cinemas this November, set in post-World War I Europe.

And now it looks like plans for the third Fantastic Beasts movie are already underway.

Author JK Rowling recently revealed: “I’ve just finished the fourth [Robert] Galbraith [Strike] novel, Lethal White, and I’m now writing the screenplay for Fantastic Beasts 3.”

She also hinted at what else she’s got coming up: “After that I’ll be writing another book for children. I’ve been playing with the (non-Harry Potter/wizarding world) story for about six years, so it’s about time I get it down on paper.”

The first Fantastic Beasts movie was released in 2016 and followed the exploits of magizoologist Newt Scamander, played by Eddie Redmayne.

Redmayne will return in The Crimes of Grindelwald, alongside Katherine Waterston, Dan Fogler, Alison Sudol, Ezra Miller, Zoe Kravitz, Callum Turner and Claudia Kim, with Johnny Depp and Jude Law.

The complete 8-film Harry Potter DVD box set is available on Amazon.
