Based on the comic book series with the same name, the Walking Dead is an American horror drama television series set in a post-apocalyptic world. The show revolves around the sheriff Rick Grimes, who discovers that the world has been infected with zombies, and humanity has almost been destroyed. He finds his family and goes on to lead a group of survivors that is in danger, both from the zombies called ‘walkers’ and from other groups of survivors. It is set in the American countryside and several metropolitan cities.
The show is currently in its seventh season, having started on cable television back in 2010, and has now been renewed for another season. Because of its long shooting periods and the years the show has been on the air, many of the characters appearances have changed over the years, as you can see from the following video.
