The Walking Dead: Behind the Scenes Featurette: Who is Lori Grimes?

The Walking Dead is a television adaptation by Frank Darabont of Robert Kirkman’s graphic novel series of the same name. The series stars Andrew Lincoln (Heartbreaker, Love Actually) as Rick Grimes, “a police officer who’s shot in the line of duty and wakes up in the hospital to find the world has fallen victim to a zombie plague. He goes in search of his wife and child.”

Jon Bernthal (Walks, Eastwick) plays the role of Shane Walsh, Rick’s partner in the sheriff’s department, and Sarah Wayne Callies (Faces in the Crowd, Prison Break) is Lori, Rick’s wife. Laurie Holden (The Shield, The Mist), Jeffrey DeMunn (The Reasonable Bunch, The Mist), and Steven Yeun (Big Bang Theory) also star.

The Walking Dead premiere was the most-watched cable series in the 18-49 demographic this year.
