THE LOST SKELETON RETURNS AGAIN takes on a whole new series of clichés, primarily drawn from those low budget adventure epics -- rich in potted ferns and stock footage -- that thrived on cheap back lots from the early 30s to the late 50s. It also wanders beyond the narrow confines of jungle pictures, parodying everything from gangster movies to those Mondo films of the 1960s, with their salacious native dances.
