Chris McKay, who most recently directed The Lego Batman Moviefor Warner Bros., is in negotiations to helm the new live-action film, and Bill Dubuque (The Accountant) is writing the script.
Nightwing, aka Dick Grayson, is perhaps best known for being the original Robin. Grayson was the youngest member of a family of acrobats known as the Flying Graysons. He was created by Bob Kane and Bill Finger and illustrator Jerry Robinson, and first introduced in Detective Comics No. 38 in April 1940. After his parents were murdered, he was taken in as the legal ward of Bruce Wayne/Batman. He then became Robin and teamed up with the Dark Knight on many an adventure to fight crime in the city of Gotham.
