I do a little kickboxing, so I have some familiarity of what it takes for fighters to work  with the director and fight choreographer. 

I like how Todd Brown at Twitch  describes the scene:

“So here it is. The opening minute of the big finale, the one on one fight between  Marko Zaror and Scott Adkins that closes the film. These are two very large, impossibly agile men, going to work on each other under the expert direction of director Isaac Florentine and fight choreographer Larnell Stovall. When I sat on the jury at Action Fest this year we literally changed the rules of the competition to give both Florentine and Stovall awards – best director and best fight choreographer, respectively – now you can see why.”

The DVD and Blu-ray arrives on the streets June 1, 2010.
