Chiklis, best known for playing Detective Vic Mackey on The Shield for 7 seasons, will be donning a badge again as Captain Nathaniel Barnes, a mentor for Gordon, one he can lean on in this tough city. He will be a series regular.
Gotham’s producers had this to say:
“Captain Nathaniel Barnes lands on the GCPD like a tornado, ripping out the dead wood of Gotham’s police force. He is a law and order zealot; unafraid of making enemies – on either side of the law. For Gordon (Ben McKenzie), Barnes is a hero and a mentor, someone with whom he can share the burden of heroism. Captain Barnes proves himself to be a strong ally to Gordon… but one day he will make an equally powerful enemy.”
