ahh so you've seen the movie as well. This isn't the leg, it's a serious shoulder wound that shouldnt impair his movement.
Oh and a bullet to the leg is worse than shoulder
leg=zero to low mobility
shoulder=complete movement of body except for shoulder/affected arm is avaliable.
Until i see his body language in the movie in it's entirety, I and no others who haven't seen the movie can correctly judge whether such a shoulder impairment if it is indeed to the shoulder has been accurately portrayed (or as best it can be).
