Can anyone give some answers on this Movie? (Spoilers)

As "Eureka" is one of my favourites, I'll try to answer your questions as best I can.......

-Was the owner of the whorehouse a witch of some kind and did she make Jack find the gold?

She wasn't a witch. Frida was a madam strongly connected to nature and very intuitive. She knew both Jack's destiny and her own. Like the other women in Jack's life, she has dark hair which is significant in her connection to Jack.

~ What was the fight over with the other prospector right at the beginning?

From a narrative viewpoint, it was to illustrate Jack's independence and determination not to be helped or partnered by anybody (cf. the line "I don't need any partners"- which was also a reference to Roeg's former directing partner Donald Cammell). They were fighting because the other prospector wanted a share of the gold.

~ Who killed Jack (Hackman) was it the Son-in-Law or everyone had a part, as the assailant was kinda hidden, and the white sleeve did look like that of Hauer's?

The film is based on the true story of Sir Harry Oakes. It was an unsolved murder and Oakes' son-in-law was tried and aquitted. One of the main points is that the identity of the murderer is irrelevant- Jack "needed somebody to finish him off and he found him, just as he found the gold".

~ Did Hauer become Jack in the end?, kinda reborn via the voodoo and other powers of the stone?

No. Jack says to Claude "You want me. You want my soul" but Claude can never get it. He leaves Tracy partly because she humiliated him in court with the truth and partly because he can never have Jack's soul. The film shows Jack as the victor at the end- he gets what he wants (Helen gives up drinking, the mob leaves the island alone, Claude leaves)

~ Who were the two girls that Hauer took to the voodoo party?, they seemed to come from a HMS naval base of some kind?

They were party girls and just used to illustrate Claude as a philanderer.

~ The Mafia wanted the island as a casino; did they really think Hackman would just give this over?

No. They knew that Jack was a "dinosaur" and would have to be forcefully removed. They are everpresent- they were the wolves that surrounded Jack at the beginning.

Hope this clarifies some points. It's such an amazing movie- one of Roeg's very best.

Much as I love this movie, the courtroom scene does cause problems. Much of this is to do with Theresa Russell's hysterical performance, which wasn't entirely her fault- she was told to follow the script verbatim. The main point is that Tracy is a soul clone of her father (despite their surface differences). She emasculates her husband with the truth- "they despise you because you have me and I'm worth having. They despise me because I'm Jack's daughter and I have too much. And of course they still despise Jack because he found what they're all still looking for. I found you but you haven't found what you're looking for. You're time will come. But it's not yet". At that point, the relationship is doomed.

The final scenes show Jack (in dying) getting what he wanted- Tracy and Claude split up, the mobsters leave the island alone (cf. "They're going to have to be some changes") and Helen says "I don't drink anymore". The final scene is one of the most beautiful, heartbreaking moments in the history of film as Tracy watches her husband leave her, knowing that he could never reach the depth of understanding that would be needed to make the relationship work.

Does that answer your questions?
