Tremor's was Reba's first experience at movie making. She was perfect for the role of Heather. Heather was very rustic and outdoorsy like Reba. And I have no trouble seeing Reba as the survival type. Tremors was a Science Fiction Flick about giant mutant worms that attack the residents of a small New Mexico town. The residents get trapped and must find away to get out and also to kill the worms. Reba was definetly the highlight of this film. Tremors came out in 1989. So 1989 marks Reba's debut in the world of movies. She hasn't looked back since!
