I wonder if Chris Kyle was a Clint Eastwood fan. ‘American Sniper’’s marketing materials describe Kyle as “the most lethal sniper in U.S. history,” but before his military career, Kyle was a cowboy. He wore a hat and boots, and even carried a six-shooter. Eventually, he gave up the cowboy life and decided to serve his country. He was a gifted marksman and trained to be a Navy SEAL. But even as a soldier, Kyle never lost that cowboy swagger—or that sense that someone has to venture out into the frontier and protect the American way of life. That’s what Kyle learned from his father—who raised him to be a “sheepdog,” a watchful protector in a world of sheep and wolves—and from watching violent Westerns like the ones that made Eastwood a major Hollywood star.
