In 2004, one year after the Tremors TV series came and went and only 3 years since Tremors 3, a new entry in the film franchise came out! However, we can't have it be too much like the others, that wouldn't do well at all to bring in the monies. So what to do? Simple, set it in the same place as the first with characters very much like those found in the first, but this time IT'S A WESTERN! Didn't see that coming, did ya?
