“The Good Liar” (** out of four) was an unwieldy psychological thriller about a lifelong conman (Ian McKellen) who sets his sights on duping a millionaire widower (Helen Mirren) but soon finds that she has turned the tables on him and they both have personal ties together from the past that threaten their future. Both McKellen and Mirren are first-rate as always but story is more confusing than clever and never builds to a satisfying whole. Director Bill Condon’s first attempt at a Hitchcock thriller and likely his last.
