Harry Potter isn't the only thing JK Rowling is famous for.

Nope, she also wrote novels under the name of Robert Galbraith, and now, they're being turned into a TV show.

A new BBC series inspired by JK's novels has gotten the green light and has officially begun filming.

Cormoran Strike is a series of novels the author wrote, and like the books, the TV series will have a different name for each season.

It's based around a private investigator who is hired to look into a super model's supposed suicide, and what unravels on his search for the truth.

The debut season will be called Cuckoo's Calling, and season two, if it goes ahead, will be named The Silkworm.

JK is tweeting as Robert Galbraith and giving us little inklings into what the show will be about.

We're getting excited!
