Just watched Resident Evil. Good god there is a lot of neck-twisting in that movie! Couldn’t get this thread out of my mind the whole time I was watching it.
The head twisting ranged from the ridiculously easy (Milla one-handedly breaks somones neck by pressing their face to the left) to rather realistic (lying victim, standing aggressor with a firm grip on their arm, and a boot under the side of their jaw).
