TV Guide reports that two new cast members have joined the second season of AMC’s The Walking Dead. Scott Wilson will play Hershel Greene, and Lauren Cohan will play his daughter, Maggie. The Walking Dead is based on the comic book series of the same name by Robert Kirkman. In the comic, Hershel Greene runs a farm at which the zombie plague survivors take shelter after roaming the countryside. Maggie is one of Hershel’s few surviving children and eventually becomes a love interest for the character Glenn. Glenn is played by Steven Yeun in the AMC series. Season two of The Walking Dead will debut this fall.
