If you saw last night’s episode of The Walking Dead, then you know how complex the production must have been between the introduction of the prison, all the fighting and the hundreds of zombies.

Well, AMC has released a video of the cast and crew talk about set design, cleaning house and trying to find safety within the prison walls in the making of the Season premiere.
