Hiram Gummer (Michael Gross) was Burt’s great-grandfather and the main character in Tremors 4: The Legend Begins. He owned the silver mine that was the basis for the founding of Perfection, then named Rejection. He is completely unlike Burt, being a city slicker from the eastern United States. He came to the town when the miners were being killed off by Graboids and costing the town money. He found it hard to adjust to western life, as he was the only one there at the time that couldn’t use a weapon. The first weapon that he uses is a diminutive Sharps Pepperbox but at the end of the film he uses a Colt Gatling gun beginning his family's obsession with weaponry.
Eventually, he planned to leave Rejection and head for Carson City, believing that there was nothing he could do to help them. However, after he hocked the last of his valuables (a gold watch), he purchased the proper weapons to kill the Graboids. He was forced to discover his Burt-like side to help deal with the problem. At the end of the film, he began work on what would become foundation Burt's house. He and Christine would leave Perfection years later, but Burt and Heather would eventually move into their old property.
