In new horror movie The Secret Of Marrowbone, 26-year-old English actor George MacKay plays Jack – the eldest son of a woman named Rose, who in 1969 returns to Marrowbone, the dilapidated house in rural America where she grew up. Unfortunately, the long trip took a toll on Rose’s poor health, and as she nears death, she makes George promise that he will look after his other siblings until he turns 21 and can become their legal guardian.
