Eureka is a 1983 psychological drama film directed by Nicolas Roeg, and starring Gene Hackman, Rutger Hauer, Theresa Russell, Mickey Rourke, and Joe Pesci. It follows the life of a Klondike prospector who becomes one of the world's wealthiest men after striking gold in 1925, but, 20 years on, fears that he is being preyed upon by his daughter and her social-climbing husband, as well as a mobster attempting to usurp the Caribbean island he owns. The screenplay is loosely based on the unsolved murder of Sir Harry Oakes in the Bahamas in 1943.
