In this scene, at 5:00, you can see two people in frame and one of them shoots the other guy in the head using a shotgun. How did they edit it to look like one continuous scene? I'd imagine they would have to shoot the scene twice, once without makeup and blood, and once with makeup and blood. But how do they add these two clips together to make it look like one scene?
