Pretty neat UK commercial for coke.
As the camera pans through the house, we see the same girl, at minutely different stages of movement. The camera then moves outside, where more characters - again shown in different stages of movement – appear. In each case, the viewer thinks he’s watching a very clever time slice of each character. However, in actual fact, multiple actors play each of the characters.
