I'm not usually one for Trope Identification, but after watching the The Hobbit: Battle of Five Armies I'm dying to know if this is identified...
Is there a name for the shot/sequence wherein the camera looks up at someone who is about to strike (often POV), and as the attacker raises their hand the hand is caught (often by the wrist) before they can bring the weapon/strike down on their victim?
The hobbit features many variations of this, with the limb sometimes being amputated. It almost seemed like a running joke.
What is this called?
