Caught in the crosshairs of Michael Gross, this Graboid plummets then rises to a rude awakening. Yawing back and forth as a broken swing carrying the single chain, this subterranean squirm-a-lot navigates the dust covered canvas. Meanwhile, the great-grandfather to Burt Gummer goes by the name of Hiram (Gross). In Tremors 4: The Legend Begins, such a name proves as feeble as the man’s skill with firearms. He turns up neatly tailored and eloquent to a stuffy fault. Yet those “dirt dragons” kick the complacency out of those cufflinks soon enough.

Desperate times call for hired gunfighter Black Hand Kelly (Billy Drago, scarred and impeccable). The latter discovers the meaning behind this bullet stopping madness when he fails to penetrate the Graboids turf. He’d probably trade all the gold in Texas for an Indian war party. As such, Drago has bottled the brew for camera-loving faces. His own appears stone-cracked and beaten, the remnants of a fist-fighting youth perhaps. Overall, inviting him to this Tremors fest adds relief from the previous oil-depleted well.

Prequel splashing could spell disaster. However, director S.S. Wilson knows a good cut from the awkward kind. As before, composer Jay Ferguson injects a mean melodic pulse into this human vs worm mash-up. (Capsule review.)
