Fighting

When a director wants to create a fight scene, it is all dependant on the actors skills. If the actor cannot fight they will do quick cut shots to make it seem as though they can. A good example for this is in the Bourne Identity, where quick cuts are used throughout to make it seem like matt damon is fighting, however it is just minor stage directions he follows to create the scene.

However in other films, often chinese/japenese films, the actor can fight very well so long takes/shots are used to show off the fact that the actors can fight. Good examples of these are often used in Bruce Lees Enter the dragons etc
