Because I wasn't there during the "warehouse" fight I too also have to agree with the delivery of some of the thugs.
As for Jacqui, she actually has no martial arts experience. I do believe she has taken dance classes, though. As with most of our actresses, we just train them for on-screen fight choreography.
A majority of the guys are stunt men either at the Universal Studios or Knotts Berry Farm theme parks. The short bald one with the beard is a muay thai instructor, and the one next to him in the red top teaches some form of martial art. I forget which one. But both of them frequently film their own martial arts shorts.
The one that wore the bandana is the director/editor/producer/choreography/founder of Jabronie Pictures/ etc. He's trained in TKD and professional wrestling which is why some wrestling moves were thrown in (headscissors takeover and Octopus hold).
I only shot the stairwell fight and that was with a Canon 60D. I'm not sure what was used for everything else. Everything was edited using Premiere/After Effects CS5.5. One of our friends did part of the music using live instruments and garage band, I think.
