Following the action

Following the action is a technique that a director uses to capture the best scenes whilst a character(s) are moving about, there will be multiple cameras set up in different locations to follow then characters as they move, this gives the director a variety of different shots with different angles or zoomed in/out shots to make an entire sequence for the scene. Following the action goes into more depth to what you are watching instead of just seeing one camera shot through out, it gives the person watching something more to watch and gives it more excitement throughout the film/program. For example one of the opening scenes for Casino Royale the two main characters on screen are in a chase scene, the two characters move through out a construction site with the person being chased being adept in parkour and the chaser having to use the environment to move about, this allows the director to follow both characters moving through the environment in different  ways.
