Directed by: Brent Maddock
Starring: Michael Gross, Charlotte Stewart, Susan Chuang, Shawn Christian
Audio problem: When the guy in Jack's truck says "You better pay for that camera", his mouth doesn't match his words.
Audio problem: The federal agents from various agencies show up and basically prevent the townspeople from killing graboids, and they're arguing with Burt about it. One of the government agents yells something, and it is loud enough to clip the audio (distortion).
Continuity mistake: When El Blanco is outside Burt's home, and leaves, there isn't any hole in the ground after him. Later, in the movie, when El Blanco gets underneath the earth, he leaves a big hole after him. Why wasn't it like that the first time?
Burt: A lifetime of preparation, and I end up a refugee?
Trivia: The scene where a kid accidentally refers to a Graboid as a "Tremor" was a bit of an inside joke, as it's a common misconception among people who aren't fans of the series that the monsters are called "Tremors." It's always slightly annoyed the cast and crew, so they added the scene as a goof.
