The first picture of actor Larry Gilliard Jr as new character Bob Stookey in The Walking Dead has been released.

Entertainment Weekly says that Stookey is a former army medic who makes his debut in season four and has appeared in The Walking Dead comics and novel, The Road to Woodbury.

The show's supervising producer, Scott M Gimple, said: "His backstory is not entirely the same as in the comic and the novel. I think he's seen things go bad over and over, and winding up in this stable place doesn't shake him from his experience. He struggles with that."

Gilliard, who played D'Angelo Barksdale in The Wire, added: "You can see there's something deeper and darker that's going on with this character, just from the first episode. We don't really know what it is. We just know he's got some issues that he's dealing with."
