The Accountant's Bill Dubuque is currently writing the script for the movie, which will be based on the DC Comics character DICk Grayson.

In the comic books, Grayson is known as the first Robin, Batman's sidekick, who was taken in by the Caped Crusader after his parents were murdered. The character retires as Robin and assumes the superhero persona Nightwing.

Grayson is currently voiced by Michael Cera in MCKay's The LEGO Batman Movie.

If the filmmaker signs on to helm a standalone Nightwing, it will be his live-action feature film debut, according to The Hollywood Reporter.

Several actors including Douglas Croft, Johnny Duncan, Burt Ward, and Chris O'Donnell have previously played Robin onscreen, and in The Dark Knight Rises, it is revealed Joseph Gordon-Levitt's character's real name is Robin. It was previously thought the actor would reprise his role or take over as Batman, but he explained it is unlikely he will be returning to the Caped Crusader's universe.

"I know we're all used to the sort of Marvel movies, which are just kind of endless series," he told last year (16). "They don't really have a beginning, middle, and end. But I think (director Christopher) Nolan very much thought of that movie (The Dark Knight Rises) as a conclusion, and there's a theme that runs through all three of those movies that begins in the first movie, runs through the second movie and it concludes in that moment where he says that Batman is more than a man, Batman is a symbol. And so to have another man other than Bruce Wayne kind of becoming Batman at the end of that trilogy, I think that's the perfect ending to that story."
