Green screen everywhere
Take a look at the image above. Many fans of the show will recognize the image as the first time we are introduced to Michonne’s character. However, one thing is a little off. If you look closely you’ll notice the zombies behind her are wearing green sleeves. What this reveals is a plain and simple fact about television producing today: green screens pretty much run the show.
In fact, many of the zombies we see that have been cut in half and are merely just a torso crawling around are more victims of fancy video editing than anything else, with the actors wearing tights on their lower body to be edited out later. That’s right. The next time you see that disgusting looking Walker crawling towards one of the survivors, just remember that it’s just some dude wearing tights.
