A second trailer of Brothers has shown up:

Plot:
“A young man Tommy Cahill (Jake Gyllenhaal) comforts his older brother’s wife Grace (Natalie Portman) and her children after his older brother Sam (Tobey Maguire) goes missing in Afghanistan. Sam eventually returns and starts asking about what happened while he was missing.”

The movie Brothers is like a new variation on the theme of Cain and Abel. It is directed by Jim Sheridan and starring Natalie Portman, Jake Gyllenhaal, and Tobey Maguire.
