I shot the plates in two separate shots ->throwing the axe and taking the hit. Made a 3D panorama in After Effects. In 3D Max I modelled the axe, matched the camera and animated the axe and camera rotation. Rendered with motion blur. In AE I matched the camera rotation, imported the camera data, composited, added the blood and camera shake.
I learned that taking measurements on set will help in matching the 3d camera. The ones I needed were the angel of camera rotation and the distance between camera and characters.
