Just stumbled upon this trailer. Looks pretty mean. It's directed by the guy who choreographed the stunts in Ong Bak and directed the two sequels. Granted, some of these Thai martial arts movies can be sparse with the story, plot, and acting, but they always deliver with the ultra-violence:
It's essentially a porno with all the sexually infused money shots replaced with martial arts mayhem (i.e. it has an incredibly low budget and the acting and storyline leave much to be desired).
If one would take the time to cut out all the extraneous plot and paste together all the action sequences it would be pretty kick-a$$.
This is easily the beset fight sequence in the whole film (though there are a couple of other noteworthy ones):
I will say this about the Thai martial arts movie folks: their stunts come off way more brutal than anything I've seen come out of HK. They score serious points for never pulling their punches and never holding back on crazy feats of ridiculousness.
