Starring Pat Morita, Scott Hillenbrand, Hoyt Axton, Joseph Ruskin, and Courtney Gains, the film was released April 27, 1999.

In the film, an experiment with snake venom goes wrong and a giant, genetically engineered hybrid of an Asian King Cobra and an Eastern Diamondback Rattlesnake escapes from his lab and into a small town.

Loose in the countryside for two years and filled with the experimental aggressiveness drug, the snake, nicknamed "Seth", eventually outgrows his woodland prey and begins hunting the residents of the small brewery town of Filmore.

[1] In 2001, G. Noel Gross of DVD Talk wrote that the snake effects of King Cobra were "better than the CGI-addled Python that followed" and made note of a "hilarious cameo" appearance by Erik Estrada.

[2] Derek Armstrong of Allmovie panned the film, calling it poorly conceived and absurd, with the special effects of the snake "so cheap-looking that it can only be seen in flashes".
