Based on factual events “Alias Grace” follows the 1843 murders of wealthy Thomas Kinnear and his housemaid and lover Nancy Montgomery (played by Paquin). They were supposedly killed by two servants: Grace Marks (Sarah Gadon) a poor, young Irish immigrant and stable hand James McDermott. McDermott was ultimately hanged and Marks was sentenced to life in prison. There’s much controversy over whether Marks was instrumental in the murder or was simply an unwitting accessory. – Vikram Murthi, IndieWire http://ift.tt/2aYRGgD
