Fox described its new show Gotham as “the origin stories of Commissioner James Gordon and the villains that made Gotham famous,” the network said on Wednesday. Gordon is the police commissioner of Gotham City, and often supports Batman to defeat the city’s villains.

Each episode will be one hour, and the pilot will be written and produced by Bruno Heller, a British screenwriter best known for co-creating the HBO-BBC produced drama Rome, which explored Ancient Rome’s reign under Julius Caesar and Emperor Augustus.

Fox has yet to announce when the series will air and who will star in it. It was not clear whether Batman would be a character in the series.

Gotham will be produced by Time Warner Inc’s Warner Bros. Entertainment, which incorporated DC Entertainment, the company behind the DC Comics universe that includes Batman and Superman. The series will air on Fox, a unit of 21st Century Fox Inc.
