I. Introduction
1. Movies are constantly trying to raise the bar with wild fight scenes; seems like characters are sent flying further and further from a punch.
2. Very common for fight scenes to violate the action/reaction principle, if not completely disregard it.
II. Example 1: Hellboy (2004)
1.(32min) Hellboy is hit with a backhand that sends him flying through a row of 3 display cases and then a window, none of which slow him down.
2. Not even close to convincing; to being carrying enough force to crash through all those cases without slowing down, he would need to be going much faster.
3. Monster who hits Hellboy doesn't appear to be hitting any harder than an average boxer.
4. He would need to be swinging with a tremendous force and would show more reaction.
III. Example 2: Thor (2011)
1. (25min) Thor is able to jump what looks like easily over half a mile, at an incredible speed, yet there is no reaction on the ground beneath him.
2. Ground is ice and is shown shattering around him, every time it is hit, no reason that it wouldn't at least crack from him jumping with such an enormous force.
3. We can accept that he's a god, and can jump that far, but the ground beneath him should still be realistic.
IV. Example 3: Robocop (1987)
1. (35 mins) Robocop grabs the barrel of an automatic rifle a criminal is holding, and bends it down.
2.For the barrel to bend, the man holding the gun would have to be supporting the gun with an equal amount of force, otherwise it would simply be ripped out of his hands.
3. Man would have to be strong enough to bend the barrel himself, if he is able to hold the body of the rifle up, as Robocop pushes down on the barrel.
