Andrew Lincoln plays sheriff deputy Rick Grimes, who awakens from a coma into an apocalyptic world overrun by flesh-eating zombies. It's interesting to note that in the world of The Walking Dead, there is no zombie lore, and thus the word zombie does not exist. The undead are usually referred to as Walkers and/or Biters.
Grimes eventually tracks down his family becomes the leader of a small group of survivors. Together they seek sanctuary from both the undead and other survivors, who are often more dangerous than the zombies.
The Walking Dead premiered in October 2010 and finished its fifth season in 2015. Although the show features many character from the comic books, it's doesn't follow the in-print series faithfully, adding new character and new events, and not using others. This means fans of the comics are still able to enjoy the show with the new twists and turns the changes make.
The season five premiere garnered 17.3 million viewers, the most viewers ever for a cable TV series. A spin off show, titled Fear the Walking Dead, is set to debut in the summer of 2015.
