Terror bajo la tierra

Kevin Bacon originally resented being in Tremors, only agreeing to do it because he needed money for his new marriage and upcoming newborn child. When the film was not financially successful, Bacon feared his career was over, and in following years would refuse to acknowledge the film's existence and even called it the "worst thing I ever did." However, Bacon would eventually come around to Tremors, calling the filming of Tremors to be "the single most fun time I've ever had making a movie in my entire career" in 2012, and later admitting in a 2020 interview "When I was making Tremors, I was very depressed and at a low-point in my life, and I kinda blamed Tremors for all that. I was bitter against it, I thought it was a career-killer...I never watch my movies more than once, some of my movies I've never even seen before and have no desire to, but I've watched Tremors a dozen times. I love it so much, and I spent years trying to capture the same energy we had on the set of Tremors. It's one of my favorite films of all time."

When the remaining cast are on the bulldozer, near the end of the movie, they pull up beside Burt and Heather's house and one of the crew members is visible beside them, trying to hide.

The Italian version features an error in the cast names during the end credits, listing Burt Gummer as being played by Reba McEntire instead of Michael Gross. Reba McEntire played Burt's wife, Heather.
