In 1989, Universal released the film Tremors. Inside ths film locals of the town called Perfection are experiencing some odd events. The first was when an old boozhound named Edgar who got scared into running up a telephone pole and staying there until he died of dehydration. Soon more people are dissapearing and dying until a cause is found; massive underdground creatures that have been eating people. They emerge from the ground and grab you. Not long after is discovered that, after killing one, that there are three more of these monsters. The first of these other monsters are brought down by survivalist Burt Gummer when it breaks into his underground basement. All the people soon group together and travel across the desert toward the surrounding rock mountains because the creatures, now called "Graboids", cannot tunnel through rock. But they soon run across a trap and are forced to run to a rock formation to hide. Burt has also brought with him some bombs to help fight the monsters. He successfully destroys one of the two remaining beasts, but the last one is smart and spits the bomb back out. Everyone runs and takes cover as it lands on top of the other bombs, destroying the remaining ones. Soon three people, the main characters, are left running as the Graboid pursues. It tracks one of the men to the edge of a cliff, and he jumps out of the way as the Graboid bursts forth, flying out of the side of the cliff, bursting open as it hits the ground and dies. All of the Graboids are dead.... for now.
Tremors was a successful film. Three films came after this one: Tremors 2: Aftershocks, Tremors 3: Back to Perfection, and Tremors 4: The Legend Begins. They are all available seperately or together on DVD and on Blu-Ray in a "Tremors Attack Pack" from Universal.
