TIFF Review: 'My Old Lady' Starring Kevin Kline, Maggie Smith And Kristin Scott Thomas Mathias (Kevin Kline) is a failure. He's three times divorced, and not coincidentally, has written three unpublished novels. But the passing of his father —who has otherwise given away all his money to charity— has opened to the door to potential prosperity. Mathias' father has left him the keys to a beautiful Parisian apartment, but there's just one problem: the 90 year old Mathilde (Maggie Smith) has lived there for seventy years and has no plans to leave. Nor does she have a legal obligation to.
