"The Good Liar" is a reunion for Condon and McKellen, who previously collaborated on "Gods and Monsters" and "Mr. Holmes".
McKellen will portray a career con artist who can hardly believe his luck when he meets a well-to-do widow, played by Mirren.
As she opens her home and life to him, he is surprised to find himself caring about her.
