"It's very much a point-of-view-driven, noir Batman tale," Reeves said at the time. "It's told very squarely on his shoulders, and I hope it's going to be a story that will be thrilling but also emotional. It's more Batman in his detective mode than we've seen in the films."
The Riddler -- aka Edward Nygma or E. Nigma -- was created by Bill Finger and Dick Sprang for D.C. Comics in 1948. He is often portrayed as a prankster who taunts his nemesis Batman during a battle of wits.
Pre-production on "The Batman" is expected to start this summer.
