In this American remake of the 2004 Danish movie, Portman is fantastic as Grace Cahill, a woman grieving the loss of her husband, Captain Sam Cahill (Tobey Maguire), a presumed-dead prisoner of war.
She finds solace in Sam's brother Tommy (Jake Gyllenhaal) until he unexpectedly returns home from war, leading to chaos as he struggles to readjust, showing symptoms of post-traumatic stress disorder.
Portman's portrayal of a wife and mother trying to hold it all together brilliantly shows how war affects even those who never see combat.
