Supercroc
Supercroc is a 2007 movie about a 50-foot crocodile which is running rampant through American cities. The screenplay was written by Steve Bevilacqua, and the cast starred Cynthia Rose Hail Matthew Blashaw, and Kim Little. It is classified as a horror and action film, and was directed by Scott Harper. The movie is widely held to be a flop, and IMDb reviewers describe it as appearing to have been "made in someone's back yard."
The "Supercroc" creature of the movie is loosely based on Sarcosuchus, a massive crocodile-like reptile from the Cretaceous Period.
