Tremors is a 1990 American science fiction horror comedy film directed by Ron Underwood, based on a screenplay by Brent Maddock and S. S. Wilson, and starring Kevin Bacon, Fred Ward, Finn Carter, Michael Gross and Reba McEntire. It was distributed by Universal Studios.

The film was received well by critics and holds an 88% favorable rating at the review aggregation website Rotten Tomatoes.

The film emerged as a cult classic, followed by Tremors 2: Aftershocks, and continued in a direct-to-video sequel: Tremors 3: Back to Perfection, and one direct-to-video prequel: Tremors 4: The Legend Begins. Thirteen episodes of Tremors: The Series, a television program based on the film series, aired March through July 2003.

Valentine "Val" McKee (Kevin Bacon) and Earl Basset (Fred Ward) work as handymen in Perfection, Nevada, an isolated ex-mining settlement that contains only fourteen residents, among them general store owner Walter Chang (Victor Wong) and survivalist couple Burt Gummer (Michael Gross) and Heather Gummer (Reba McEntire). A new arrival is Rhonda LeBeck (Finn Carter), a graduate student conducting seismology tests.

A tremor is an involuntary, somewhat rhythmic, muscle contraction and relaxation involving to-and-fro movements (oscillations or twitching) of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs. Most tremors occur in the hands. In some people, tremor is a symptom of another neurological disorder. A very common kind of tremor is the chattering of teeth, usually induced by cold temperatures or by fear.

Tremor can be a symptom associated with disorders in those parts of the brain that control muscles throughout the body or in particular areas, such as the hands. Neurological disorders or conditions that can produce tremor include multiple sclerosis, stroke, traumatic brain injury, chronic kidney disease and a number of neurodegenerative diseases that damage or destroy parts of the brainstem or the cerebellum, Parkinson's disease being the one most often associated with tremor. Other causes include the use of drugs (such as amphetamines, caffeine, corticosteroids, SSRI), alcohol abuse or withdrawal, mercury poisoning; this is also in infants with phenylketonuria (PKU), overactive thyroid or liver failure. Tremors can be an indication of hypoglycemia, along with palpitations, sweating and anxiety. Tremor can also be caused from lack of sleep, lack of vitamins, or increased stress.^{[citation needed]} Deficiencies of magnesium and thiamine have also been known to cause tremor or shaking, which resolves when the deficiency is corrected. See magnesium in biology. Some forms of tremor are inherited and run in families, while others have no known cause. Tremors can also be caused by some spider bites, e.g. the redback spider of Australia.

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
