Ever notice that when a good guy and bad guy are fighting, the bad guy only has to walk slowly, menacingly towards the good guys. I mean the good guy will be running, full sprint away from the bad guy, and the bad guy just walks slowly towards them. Somehow bad guys defy the laws of physics and end up in front of the good guy and ambushes them. How do they do that? Do they just burst into a full sprint when the camera is off them?
