Filming for The Walking Dead‘s third season began a few weeks ago, and now AMC has released the first still from the premiere episode.

In it, we see lead character Rick Grimes pointing a gun — at a zombie? At one of his people? At a new character altogether?

The Walking Dead‘s third season will see the characters taking shelter in the prison and meeting new characters like The Governor, played by David Morrissey.
