Rumor has it that the pilot will be filmed in California. A Reddit user supposedly got a notice that their town may be used for shooting the pilot.
This goes against the supposed casting in Pennsylvania. However, the pilot could be shot in California, then the rest of the series shot in Pennsylvania to save costs. Time will only tell for these details.
The pilot episode of the Walking Dead spinoff is titled Cobalt. Two cast members, Frank Dillane and Alycia Debnam Carey, will play siblings, two of the six main characters I had outlined in a previous post. They should be interesting characters, though I’m curious to see more casting decisions. Check out my previous post here for information on the casting call.
