Eureka

Hackman stars as Jack McCann, a gold prospector who strikes it rich beyond his wildest dreams. But having achieved his goal, Jack now finds his passion for life drained; there is no longer anything to drive him. Arrogant and abusive, he becomes obsessed with the motives of those around him, suspicious that even his own family, in their jealousy over his wealth, could make him pay the ultimate price.
