Just the other day we posted a brief promo spot for Gotham, which took us a little bit further into Bruce Wayne's future Batcave. Today we have a series of promo photos featuring all the main characters that will see in the upcoming second season.

Everyone knows the name Commissioner Gordon. He is one of the crime world’s greatest foes, a man whose reputation is synonymous with law and order. But what is known of Gordon’s story and his rise from rookie detective to Police Commissioner? What did it take to navigate the multiple layers of corruption that secretly ruled Gotham City, the spawning ground of the world’s most iconic villains? And what circumstances created them – the larger-than-life personas who would become Catwoman, The Penguin, The Riddler, Two-Face and The Joker?

Gotham is an origin story of the great DC Comics super villains and vigilantes, revealing an entirely new chapter that has never been told. From executive producer/writer Bruno Heller (The Mentalist, Rome), Gotham follows one cop’s rise through a dangerously corrupt city teetering on the edge of evil and chronicles the birth of one of the most popular super heroes of our time.

The series stars Ben McKenzie, Donal Logue, Sean Pertwee, Robin Lord Taylor, Erin Richards, David Mazouz, Camren Bicondova, Zabryna Guevara, Cory Michael Smith, Victoria Cartagena, Andrew Stewart Jones, and John Doman. Some of the newcomers include James Frain and Jessica Lucas as Theo and Tabitha Galavan, and Michael Chiklis as Captain Nathaniel Barnes.

Gotham Season 2 is set to premiere on September 21st.
