Intro: Because actions shots are more emotional and use tension to sell a scene, there are a lot of mistakes in action sequences in terms of inertia.

1. Batman: Under the Red Hood
Batman shoots a grappling hook to snag Red Hoods leg, but doesn't mess up his jump trajectory

• but even the split second it hooks on before he cuts it, it should be enough to mess up his jump arc
• the strength of his jump has to over exceed the speed of the grappling hook for this to barely make a factor.
• If something snags the leg for even a second, its a force powerful enough to create a reaction.

2. James Bond: Quantom of Solace
 Bond and villain smashes into the roof while swinging with ropes and tumbles down, Bond however gets his leg caught in the rope mid-fall and that breaks his fall, rather than his ankle.

• From that high of a fall, it should at least break his ankle if it does properly break his fall.
• Because an adult weighs a lot, he would be falling at a speed fast enough to shatter his leg AND slam his face into the ground instead of dangling safely.
• The height of the roof doesn't help, in fact it should contribute to the speed that he should be falling in.
• the ankle doesn't have enough strength to hold an adult male's weight and the combined force of his acceleration and his weight.

3. Iron Man 2
When Iron man and War machine crash land back into the stadium and they stand up just fine afterwards.

• moving at missile speed and crashing down will not only damage the suits, but because human flesh is soft.
• Because of the high acceleration and the sudden stop on the suit, the body should be completely wrecked by the impact because it's still in motion.
• It doesn't help that humans weigh enough for the damage to matter.

Conclusion: Action movies tries to blur reality by pushing tension in a shot, science and the laws of inertia says otherwise.
