In the scene where Brad Pitt is shooting the man in the foot so he can't go back to the city, he shoots the man in the right foot. Later on in the movie, near the end, Brad sees the man in the car-with a cast on his LEFT foot!
I think your incorrect. If you mean when Jerry gets punched in the face and knocked out then taken away by the guy whos foot he shot. You will clearly see it's his right foot that has the cast on it.
