This movie was filmed partly on the island of St. Lucia in the Caribbean. Unfortunately, the directors didn't pay enough attention to some of the local speaking "extras" who, in the scene with the young boy in the town of Soufriere, one of the locals curses a certain part of his mother's reproductive anatomy in the local Creole dialect - Patois. Oops!!!
This is based on the Peter Benchley novel "White Shark". After the TV Movie "Creature" went into production, "White Shark" was re-titled and re-released under the name "Creature" to cash in on the movie.
In the original novel, Chase is not a scientist but a private citizen who has founded an institute, and Dr. Amanda Macy is not his son's mother. The creature is a surgically altered homicidal maniac, not a genetically created monster.
