The Phantom Empire

In this bizarre blend of action, adventure, and comedy, a man-eating cave creature wreaks havoc on a public park, leading to a treasure trove of uncut diamonds worth $500,000. Denae Chambers, daughter of the late Dr. Chambers, hires adventurers C&C Salvage to find the source of the gems, which may lead them to the fabled underground kingdom of Rilya. With a cast of eccentric characters, including grizzled Cort Eastman and cynical Eddy Colchilde, this 1988 film is a loose re-imagining of the classic 1935 serial "The Phantom Empire."
