El cazador de tiburones (Il cacciatore di squali)

A tormented shark hunter from a Caribbean island gets involved in the search for 100 million dollars that are buried in the wreckage of a plane crash. Castellari's first foray into sharksplotation is an entertaining adventure of treasures and smuggling, where the underwater action with sharks is perfectly combined with a superb soundtrack by Guido and Maurizio De Angelis, not to mention the director's own appearance as a hired killer.
