On paper, none of this should work: the cartoon story of a stereotype of New Jersey (he might just as well live down the street from Jersey Shore) who's addicted to porn, and weaned from his vice by the loving ministrations of a good older woman. But Joseph Gordon-Levitt, who wrote, directed, and stars, gently maneuvers around cliché, assisted by Scarlett Johansson's bubblicious comic-vavoom turn as the objectified girl of our Jon's dreams, and Julianne Moore as the Real Woman. —Lisa Schwarzbaum
