Well, his head was anyway. The noggin furthest to the right was actually molded to look like Depp. Here's an explanation from the director of The Walking Dead, Greg Nicotero: "I think we had sculpted an emaciated version of a dummy head for something and we used Johnny Depp's head as a basis just for a clay sculpt." But... why? Maybe Depp has secretly always wanted a cameo on the show! Congrats bud, you got it.
