J.K. Simmons has confirmed he is returning to the role of Commissioner Jim Gordon in Batgirl, and he promises it is a “significant role.”

Simmons appeared on a recent episode of Happy Sad Confused and not only confirmed his involvement with the film, but also spoke briefly to what we can expect from it.

“I was completely flabbergasted they came back to me recently and wanted me to be Commissioner Gordon again and have it be a more significant role,” said Simmons. “I’m looking forward to it. I think I’m going to get on the horn to [Leslie Grace] and the directors in the next couple of days and do little preliminary rehearsals.” He went on to add, “They start very soon and I jump on board sometime in January in Glasgow which is a wonderful place to shoot it as it’s Gothic.”

“I’m excited to be the once and future Jim Gordon,” Simmons continued. “I had a long discussion with the guys about how we want to portray him. It’s a really interesting take on introducing Batgirl and fleshing Jim Gordon out.”

Adil El Arbi and Bilall Fallah will direct the film and are currently in Scotland preparing for the production. Christina Hodson (Bumblebee, Birds of Prey) wrote the film’s script. Leslie Grace will be playing Barbara Gordon/Batgirl, and Brendan Fraser has been cast as the villain.

No release date has been announced for Batgirl as of yet.
