I don't know if it's news, but it really took me by surprise just how much of what we see in movies and television is computer generated. Sure, I'm already aware that whenever a character is shown watching television or using a computer, I know that the actor is really looking at a green or blue screen, because the glare from the screen does not show up well of camera.
But I never knew actors work with green screen this frequently. So the next time you watch any television show, may it be The Walking Dead or whatever, try to spot what's real and what's not. Special thanks to @OMGFacts.
