Matrix, The - Agents Wrists of Steel... Sometimes?
Please watch anytime an Agent fires his .44 or .50 caliber Desert eagle pistol before "killing" Neo towards the end. The explosion inside desert eagle, let alone any pistol would create what's called recoil, propelling the pistol backwards, and therefore also the user's hand. The agent's pistols up until the end have no recoil, and you can ask anyone who knows the slightest bit about firearms, a desert eagle is very powerful, and the violent recoil can break someone's wrist. The agents can just keep firing, as if the gun were a water pistol.
At the end, where Agent Smith shoots Neo in slow motion, miraculously, with each shot, his elbow bends back, in realistic recoil. Sadly, when the picture goes back into realtime motion, his hand stays still while cappin Neo in the chest.
