One of Hollywood's favourite faces of all time - Johnny Depp, makes a cameo appearance on AMC's "The Walking Dead", as reported by Vanity Fair. The show, which has always been known to feature famous musicians like Scott Ian and even football player Hines Ward, has now stepped their game up by featuring arguably the most famous musician by far: Johnny Depp, who is the guitarist of Hollywood Vampires.

Although, it was not actually Depp himself, but his head. Greg Nicotero, producer and special effects guru who directed the episode, revealed to Entertainment Weekly that while one of the severed heads which was meant to look like Xander Berkeley's character Gregory was based off his own head, another one was actually based off Depp's.

"I don't know if I'm going to get in trouble if I say this, was Johnny Depp. 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. I can't remember who the third one is, but I'm in good company," Nicotero stated. "Norman kept saying he wanted the heads when we were done shooting. I said we've got to wait until the picture is logged."

Nicotero also had a knock off finding out that Gregory's head was actually his. "It's kind of funny because a lot of people ask me how many cameos I do in the show as a walker. The Gregory head is actually a cast of my head," he said.

"When Xander Berkeley was cast as Gregory, we didn't have enough time to get him to Los Angeles to do a head cast and make a dummy head of him, so I sent photos of him and I said, 'Here's a picture of the actor. Let's see what we have in stock that looks as close to Xander as it can be.' It ended up being a mold of my head. So that head that he picks up is actually a fake head of me!" Nicotero added.
