Andrew Prine, Denise Crosby, Patrick Reynolds, Conan Lee, and Roy Dotrice in a children’s adventure film from Empire Pictures. As usual in the genre, Spielbergism runs rampant—particularly in the figure of Prine’s wily, ironic charter-boat captain, a clone of Indiana Jones—but director Peter Manoogian brings some decent pacing and a refreshing touch of naivete to this yarn about a lady scientist, a half-human robot, and a kung fu master who band together to crush a mad doctor in the jungles of Central America. The extreme low-budget production conjures its own kind of charm, bypassing Spielberg’s inflationism to return the pulp material to the grade-Z context where it was born and belongs.
