Heather Gummer was the wife of Burt Gummer in the first film. Like Burt, she is a firearms enthusiast. The two worked as a team in being prepared for defending themselves. However, because McEntire chose not to reprise her role Heather left Burt. It was stated that sometime between Tremors and Tremors 2: Aftershocks, she left Burt when he became too paranoid even for her and she divorced him and moved away. Burt still cares for her apparently as he uses her name ("Heather") as part of the passcode of his bunker's security system.
- Reba McEntire sang the closing song of the first movie.
