Shot reverse shot

Again, as like 'Match on action' shot reverse shot is quite s simple technique but also very effective and used in basically all movies known to man.

Shot reverse shot is a film technique where one character is shown looking at another character (often off screen), and the other character is shown looking the opposite direction to imply that both characters are looking at each other. A simple and very effective illusion and also means that only one actor/actress is used at a time.

42-43 Seconds is a very easy example of opposite camera angles that implies that both characters are looking at each other.
