Billy Bob Thornton Does Redneck Hsing-i Kung Fu?

I've been thinking quite a bit about close-range fighting lately, and remembered this great scene from an otherwise depressing movie, "Chrystal".
I won't cover the plot too heavily, but Billy Bob Thornton's character has to settle a score with a former rival in this scene.
What I find interesting is he is basicly using a redneck form of the Chinese internal art Hsing-I. Now, this is not true to the actual art, but the two big techniques he uses are a chop-kick to the shins and knees, and a heavy overhand palm strike or slap.
Let me say, I love this, and this is kind of how I close the gap also. In true Hsing-I, the practitioner would not retract the kick and keep the gap open. He would instead drive through the opponent, "occupying" his space.
None-the-less, this is a pretty good representation of how a low kick to the shin or knee sets up a great overhand slap.
I am curious who choreographed the fight scene...
