Last week the still untitled Walking Dead spin-off was given a two season order from AMC. Not much is known about the series other than it will be set in Los Angeles with Cliff Curtis, Kim Dickens and Frank Dillane leading the cast. Previous reports suggested that the spin-off would be a prequel, but writer and producer Robert Kirkman has revealed that the new series will eventually take place in the same timeline. 

"From the beginning of the show one thing we've heard is, 'What's going on over here or there'. So the intent of the new show is to expand that world and show another corner of the United States and what's happening there. 

The timeline is taking place a little bit earlier than the original show. Rick Grimes woke up from a coma and was like, 'Oh, man, zombies, weird!' We're going to possibly see that unfold a little more in the other show. But I wouldn't call it 'prequel' because the entirety of the show is not going take place before [The Walking Dead]. It will eventually form a path running concurrently."

Kirkman also commented on how minor events from The Walking Dead could tie into the companion series, but ultimately the new show will be accessible to audiences unfamiliar with The Walking Dead.

"One thing that we're doing with the new show that we're trying with everything is it's not derivative. It's standing on its own. You can watch it by itself and get your own experience. But if you are watching both shows there are things like, 'Oh they discovered this, or they discovered that in a different way'.

There are a lot of things about The Walking Dead world these characters have to learn or figure out to get by. And there may be some things that are discovered in the companion show that haven't been discovered in the other show yet.

So there could be like a thing where, 'Oh, they encountered a zombie in season four in The Walking Dead that could do this and now we know why that was'. So we're going to be doing things like that are going to be pretty cool, but for the most part [the two shows] should be able to stand alone.”

The spin-off series is expected to be broadcast sometime over the summer; the first season will be  six episodes just like the very first season of The Walking Dead. The second season will likely consist of a longer run although the exact episode order remains unknown.
