The following video illustrates how director Alfonso Cuarón did those amazing long takes in the movie "Children of Men" starring Clive Owen and Julianne Moore. I couldn't figure out how they did this (I figured a lot of green screening + editing) to get this to work. I was way wrong. What they've done will probably revolutionize how shots are done in a car.
