Killing Season (2013) (Click on the title for my full review.)

The cast includes Robert De Niro, John Travolta, Milo Ventimiglia, and Elizabeth Olin.

The film is written by Evan Daugherty  and directed by Mark Steven Johnson.

DeNiro and Travolta play veterans of the same war who have become friends.  Eventually their friendship turns sour and they wage a new war against each other.

Both actors may be getting old (especially DeNiro), but this movie looks entertaining and intriguing enough for me to want to see it.

The film is set to release on 7/12/13.
