At first, all you can notice is how damn young everyone looks. Capt. Sam Cahill (Tobey Maguire) has the bearing and attitude of a grown man, but looks small and scrawny when uniformed as a Marine. He and his wife Grace (Natalie Portman) have two daughters, both well out of toddlerhood, and yet when they shepherd them through the living room or seat them at the dinnertable, they look like nothing else so much as two kids playing house. Sam's brother Tommy (Jack Gyllenhaal) is the only one here who really looks his age - yet as if to compensate for this physical maturity, he's the most immature in behavior, picking fights with his dad, getting drunk, banned from driving the car as if he's a 16-year-old who's been grounded. These characters hover uneasily between the youthfulness of their appearance (and perhaps the youthfulness of the roles we associate them with) and the gravity of the world they inhabit. The three characters - posed like Calvin Klein models in Brothers' weird poster - must face death, trauma, war, and the disintegration of a marriage, while raising children and trying to maintain their own sanity. They do this, or attempt to do this, as adults; this is one of the first movies to treat the Millennial generation as grown-ups.
