“Brothers” is the upcoming Natalie Portman-Jake-Gyllenhaal-Tobey Maguire movie about the Iraq war. Sam (Tobey) goes off to fight, leaving Grace (Natalie) and two kids at home, and he dies. Grace and the kids are heartbroken, and Tommy (Jake) steps in to help out (and, apparently, sleep with his dead brother’s wife). But wait! Sam isn’t dead! He comes back home, and things start going back to normal, but then he loses it when he finds out about Grace and Tommy! And his daughter tells him at the dinner table that Mommy would rather sleep with Uncle Tommy than him! And Sam goes apeshit! Looks like a much more intense, much less sappy version of “Pearl Harbor,” with its Ben Affleck-Josh Hartnett-Kate Beckinsdale love triangle, no?
