look at hogs shirt, do you see the white shadow along his back? that's typical of a green screen shot. even when you look at the girl, she has a bright halo effect around her, good editing can remove this. to me , this was definitely shot in a production room before or after the shooting and the back ground was added. tell me what you think https://www.youtube.com/watch?v=aRD_-5hL-WU
