Yes, it was filmed entirely in Texas, (as proudly stated in the credits), even though the film offered a quick panorama of a Mongolian plain at the start of the movie. The lead male star took a night off from his Friday night bowling league to make the movie, yet he is the highlight of this very badly acted mess-terpiece. With a sewage plant as the film's centerpiece, some cardboard shacks for additional props, and very poor CGI effects, the term "low-budget" is something of an understatement. The typical B movie lures, naked girls in the shower, buckets of red paint sloshed about in the death scenes, are all missing from this one. And, as other comments have noted, the supposed native characters look mostly Chinese or Mexican, not Mongolian. The "sheriff" looks like he walked right out of some small Texas town to join the movie. Something was definitely missing from this flick.
