“People see the movie poster, and it’s got a guy and the American flag, and they know Clint Eastwood—the Dirty Harry guy and the Republican convention guy—directed it,” Hall told Time. “So they think it’s some jingoistic thing. I would challenge that in a big way.”
Some critics say the film is glorifying a murderer, while Hall stands by his screenplay as a ”portrait of a beleaguered soldier” in Chris Kyle. According to Hall, he saw a different side of Kyle outside of the war following his death.
