8 Tips on how to portray convincing fights on the screen.
Tip 3 : Motion
A static fist-fight looks dated and unexciting. Fights are dynamic and violent, and to achieve this feeling you can dictate the movement of the camera by the movement of the actors as they struggle and drag each other around the room. For example, if you start with a medium shot set up alongside the actors around head height, as they struggle one actor should drag or push the other across the room, perhaps into a wall. The camera should move with the actors across the room, without changing the height, pan angle or distance to achieve the strongest feeling of movement.
The actors will not be completely even as they move across the room, and if you follow them as a pair it will diminish the sense of motion that you are trying to achieve. Instead, keep the camera focused on only one actor, to maintain the dynamic feeling of the shot. Once the actors come to a stop against the wall, you can change the height, distance or pan angle, as this will emphasize that the dynamic motion of the shot has ceased.
