When fans think of the upcoming season 3 of “The Walking Dead,” they are most likely anticipating the introduction of new characters Michonne and the Governor. However, they aren’t the only new characters this season. AMC has announced that Dallas Roberts will be appearing as the character of Milton, one of the residents of Woodbury.

Robert Kirkman, comic book creator and series executive producer, explained,

“Milton is the details guy. He’s the guy that works with the Governor, who is monitoring all situations and is trying to help the Governor make sense of this world that they’re living in. He’s not exactly a scientist, but he’s a smart guy that is trying to find out how zombies behave. Watching him do his little experiments is going to be a lot of fun.”

According to the series showrunner, Glen Mazzara, fans will see Milton being not necessarily an imposing threat on the gang, but more of someone attempting to make themselves useful in a terrible situation.

“We were examining, ‘How do people survive in this apocalyptic world, and what can people contribute?’” says Mazzara. “And we didn’t think it was plausible that every single character we meet is an efficient zombie killer. We just didn’t buy that everyone we know would be active and deft enough to kill every walker. We wanted to show how other people survive, and Dallas has come in and helped us establish that character. He just adds a lot of heart and humanity to Woodbury, which further complicates what that is. That is a real town with real people and real survivors. It’s not necessarily a group of bad guys.”

The third season of “The Walking Dead” is set to premiere on October 14, 2012 and will feature 16 episodes.
