After Roger Corman produced Dinocroc (2004) in 2004, he wanted to create a sequel to be named Dinocroc 2. However, the Sci-Fi Channel turned down the project after claiming that sequels did not do well for them. Corman decided to go ahead with the project anyway, but under the title Supergator.
The roar of the Supergator is taken from the Spinosaurus and the Velociraptors from Jurassic Park III.
Screenwriters Marcus Dunstan and Patrick Melton (Feast, Saw IV) appear briefly during the attack on the luau. Dunstan is one of the people eaten by the alligator.
The film debut of Tamara Witmer.
It has never been released onto home video in the US.
