AMC’s “The Walking Dead” is based on the comic book series written by Robert Kirkman and published by Image Comics. Kirkman serves as an executive producer on the project and three-time Academy Award-nominee Frank Darabont (The Shawshank Redemption, The Green Mile) serves as writer, director and executive producer. Gale Anne Hurd (The Terminator, Aliens, Armageddon, The Incredible Hulk), chairman of Valhalla Motion Pictures, serves as Executive Producer. David Alpert from Circle of Confusion and Charles “Chic” Eglee (Dexter, The Shield, Dark Angel) serve as Executive Producers.

“The Walking Dead” tells the story of the months and years that follow after a zombie apocalypse. It follows a group of survivors, led by police officer Rick Grimes, who travel in search of a safe and secure home. The comic goes on to explore the challenges of life in a world overrun by zombies who take a toll on the survivors, and sometimes the interpersonal conflicts present a greater danger to their continuing survival than the zombies that roam the country. Over time, the characters are changed by the constant exposure to death and some grow willing to do anything to survive.

Shot on location in Atlanta, “The Walking Dead” is led by a cast that includes Lincoln (“Teachers,” Love Actually) as Rick Grimes, Jon Bernthal (“The Pacific,” The Ghost Writer) as Shane Walsh, Sarah Wayne Callies (“Prison Break”) as Lori Grimes, Laurie Holden (“The Shield,” Stephen King’s The Mist) as Andrea, Jeffrey DeMunn (Stephen King’s The Mist, The Green Mile) as Dale, Steven Yeun (“The Big Bang Theory”) as Glen, Emma Bell (The Bedford Diaries) as Amy and Chandler Riggs (Get Low) as Carl Grimes.
