Created by Dominic Mitchell, the thriller series is about teenager Kieren Walker, a Partially Deceased Syndrome sufferer who continues in his struggle to find acceptance.
The six-part, second season, a BBC America co-production with BBC Drama Production North, is to premiere in 2014. The show co-stars Emily Bevan, Harriet Cains and Stephen Thompson.
"The first season of 'In the Flesh' introduced a twist to the zombie genre that compelled us to see the mind of the 'undead' in a different way, making it a seamless fit for BBC America's Supernatural Saturday programming block," Richard DeCroce, BBC America's senior vice president of programming, said in a statement. "We can't wait to see what lies ahead in the second season as we dig deeper into the emotionally yet thrilling town of Roarton.
"With its uniquely naturalistic take on the zombie genre, told as much from the point of view of the zombies, or PDS Sufferers themselves as that of the locals forced to live alongside them, 'In the Flesh' is original, dramatic, funny, politically engaged and never less than 100 percent emotionally truthful," said director Jim O'Hanlon.
"It's rare to find a series that is so exciting, entertaining and humorous, yet has so much to say about the world we live in today. The characters have genuine verve, wit, color and depth and I can't wait to get started on bringing them to life."
