Tremors are usually the first symptom of mercury toxicity. The tremor usually begins in the face, then progresses to the hands. Later the tongue is affected, speech becomes slow and slurred and the gait becomes ataxic. The tremor is an intention tremor, meaning that the more one tries to control it, the worse it becomes.

Tremors: The Series was released in 2003 by the Sci-Fi Channel. It is a spin-off of Tremors and was produced at the same time as Tremors 4: The Legend Begins. Though Sci-Fi's highest-rated program at the time, it failed to hit the demographic that Sci-Fi wanted and was cancelled after one season of 13 episodes.
