This movie will be a HUGE box office failure.
In the US, yes. But internationally, it will probably do fairly well. For example, "In the Valley of Elah", another anti-war movie, generated a paltry $6M domestically, but made another $22 million internationally. The good news is it probably didn't recoup its production, marketing and distribution costs. "Rendition", another clunker, made $9.7M domestically and $17M internationally. It too probably lost money as a whole, but these movies aren't made to make money. They're made to make a political point, and they're financed by the studio's other more commercially successful releases.
Summit Entertainment is releasing "Fair Game". Summit has released a couple commercially successful movies in its 14-year history - like "Knowing" ($79M), but it's swimming in cash recently because it is the studio that owns and distributes the "Twilight" movies - which have of course have generated close to a billion dollars in box office and home video sales. Essentially, the American teenage consumer is underwriting "Fair Game". That's how Hollywood works - they sell crap to our kids so they can afford to lose buckets of money on their anti-American screeds.
