It looks like prolific author and newly-minted screenwriter J.K. Rowling may have already completed yet another script for an upcoming sequel to last year's "Fantastic Beasts and Where to Find Them," proving that the writer is definitely ready to share more stories from the Wizarding World.

Rowling shared on Twitter a cryptic photo of what appears to be the cover of a script for another film in the planned five-movie "Fantastic Beasts" franchise (a prequel to the massively popular "Harry Potter" stories), spurring speculation that she's now completed work on the third feature in the series. Of course, in typical Rowling fashion, the teasing image doesn't exactly give anything away -- or really, even reveal what it truly is -- only including the text "Written by J.K. Rowling," and some legalese from studio Warner Bros.

There's no visible title, and Rowling's caption was also pretty vague, simply stating, "Having a Beastly day." Still, considering that she'd already completed the script for the second film in the franchise before the first even hit theaters, it stands to reason that this is an announcement that the writer is now done with the third film, too. (Another possibility: It could be revealing that production on "Fantastic Beasts 2" is about to start.)

Rowling shocked fans -- and even the film's stars -- last fall when she announced that the "Fantastic Beasts" series, originally planned as a trilogy, would instead consist of five movies. The cast has since assured fans that Rowling has a clear, epic vision for these stories, and based on the pace at which she's completing work on scripts, it looks like the author can't wait to tell them.

We can't wait, either. "Fantastic Beasts and Where to Find Them 2" is due in theaters sometime in 2018. No word yet on when the third flick may debut.
