I've noticed in old movies (like from the 40s, 50s, etc) when they are driving in a car, that the scene is filmed with a stationary car, and typically, filmed from the front of the car, with the scenes moving in the back window. I believe these were scenes moving past on sheets of paper if I'm correct.
This similar technique seems to be used in TV shows like comedies even now, at least that's what it looks like to me. The car is not actually moving. But nowadays it would be done via a green screen I would assume, where some kind of digital video is taken of the actual street for the background and superimposed.
However, in some shows, like dramas, it appears that the character is actually driving the vehicle. Sometimes I've heard that the car is placed on a trailer, and then the car is filmed without showing the trailer. It simply looks low enough to the ground that you can't tell.
But I have seen some scenes in TV shows where it's filmed from inside the vehicle, and you can definitely tell that it's actually being driven by the actor, as the gear is in place, and the speedometer is showing the speed.
I just wonder how they do this, and I would assume that if this kind of scene is being filmed, whether inside or outside the car, the street probably has to be closed to any outside traffic? So if you see cars going by outside the car, or through the windows if the scene is filmed inside, then those cars are also driven by actors.
I've noticed also, that sometimes the rear view mirror is taken off in some scenes, yet in the next view, it's back in place. And sometimes the headrests are removed, or lowered in some scenes, but in next scene the headrests are pulled up again.
Also many times when I see driving scenes from outside or inside the car, the driver's window is usually always lowered, or both front windows. I did see one scene filmed inside the car, with windows up, and they showed the dashboard and the A/C was turned on for some reason. I figured it would be off for filming, to cut down on background noise.
Anyone else notice this? Maybe I just notice details too much.
