The New Line Cinema drama “The Good Liar” pairs Oscar winner Helen Mirren (“The Queen”) and two-time Oscar nominee Ian McKellen (“Lord of the Rings: The Fellowship of the Ring,” “Gods and Monsters”) on the big screen for the first time. Bill Condon, the Oscar-winning screenwriter of “Gods and Monsters,” directed and produced the film from a screenplay by Jeffrey Hatcher (“Mr. Holmes”), based on the widely acclaimed novel by Nicholas Searle. Career con artist Roy Courtnay (McKellen) can hardly believe his luck when he meets well-to-do widow Betty McLeish (Mirren) online. As Betty opens her home and life to him, Roy is surprised to find himself caring about her, turning what should be a cut-and-dry swindle into the most treacherous tightrope walk of his life.
