Of Russ Meyer's wild canon, Up! is easily his most frenetic film, a nonstop frenzy of nudity, gore, and bawdy humor that only occasionally makes sense. Never a director to waste much time on character development or motivation, Meyer is even more focused here on sheer action, to the point where viewers can only give up and let the gorgeous scenery and ridiculous proceedings wash over them. As the '70s progressed, Meyer's films became more outrageous in terms of sex and violence, and Up! is no exception, with cartoonishly gory axe fights, a vicious rape scene (with comical "Boiiing!" sound effects), and endless noisy couplings in police cars, showers, and mountain streams. The convoluted plot concerns some sort of Nazi conspiracy and will require repeated viewings to understand, though each ride through the beautifully photographed woodland pines will provide giddy enjoyment to those who love low-brow excitement. It's hardly the best place for neophytes to begin exploring Meyer's bizarre macho universe, though fans who haven't experienced the film will love the addled rush of images and action, whether it all adds up to a coherent story or not.
