Sir Ian McKellen stars as a heartless elderly con artist who can hardly believe his luck when he meets a wealthy widower (Helen Mirren) online. But our protagonist's dastardly plan starts to fall apart when he finds himself caring about his mark—who may be significantly less helpless than she appears. There's a comfortable pleasure in seeing McKellen and Mirren's first onscreen team-up. But the film's countless twists and turns are too tame and tidy to elicit many thrills. 109 minutes R.
