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.

In 1925 in the Yukon, prospector Jack McCann spends the evening in a remote brothel, where he has a spiritual experience with the madam, Frieda, a clairvoyant who bestows him a mysterious stone.

Twenty years later in 1945, he lives in luxury on a Caribbean island that he owns, in an estate named Eureka.

However, Jack's wealth brings him no peace, as he copes with Helen, his bored, alcoholic wife; Tracy, his headstrong daughter who has married Claude Van Horn, a dissolute, philandering social climber; his paranoid assistant Charles Perkins; and Miami mobsters led by Aurelio D'Amato sent by crime boss Mayakofsky, who wants to acquire Jack's island and build a casino there.

In response, Pete brutalizes Jack, bludgeoning him in the head with a wrench before meticulously burning him alive with a blowtorch as he lay helpless in his bed, and then decapitating him with a cleaver.

The vicious murder is witnessed by Claude, who returns to the house in the midst of it, as well as by Charles, who was sleeping in an adjacent bedroom.
