Take heart, zombie fans. Co-creator Robert Kirkman is working on a spinoff series that expands the world of the hit TV show, The Walking Dead. The news comes on the heels of AMC Networks (AMCX -0.16%) announcing plans to develop a spinoff for another of its hit shows, Breaking Bad.

Plans call for the new series to air in 2015. It'll also be an entirely new property. While The Walking Dead is based on the comic book of the same name, Kirkman's new series will be set in the same world, but feature new characters and original storylines.

Don't be surprised if investors bid up AMC stock in response... especially when you consider how the studio produces and distributes The Walking Dead, Fool contributor Tim Beyers says in the following video. Watch now to get the rest of the story.
