It's not much of a movie. But raging bull Robert De Niro, suited up to play for humor and heart, proves he can be a world-class charmer. He plays Ben Whittaker, 70, a retired widower hired as an intern for a Brooklyn e-commerce fashion house run by Jules Ostin (Anne Hathaway), a workaholic wife and mother who doesn't know what a geezer can teach her until, well, she does. That's it — pure fantasy piffle from writer-director Nancy Meyers. De Niro makes it go down easy.
