(FOXNEWS) — While audiences across America united to give "American Sniper" the biggest ever opening weekend for a movie in January, the Clint Eastwood film has some in Hollywood at odds.
The war drama, which grossed over $100 million over the weekend and received six Oscar nominations, is based on the life of Navy SEAL Chris Kyle who served four tours in Iraq and was called the most lethal sniper in U.S. military history.
While Kyle's actions earned him multiple commendations of valor for his service in the military, one Hollywood documentary-maker was not impressed.
