It’s strange to watch old films and see how some things are so dragged out. In older films you might see an actor park their car, get out, grab things form the car, walk to their door and unlock it all in one shot. Modern editing would show the car pull up, have brief shots of them getting out, then we’d see them arriving at the door and starting to unlock it before cutting to the door being opened from the inside. Efficient editing has been refined down to a science.
