11. Clint Eastwood

One of the original tough guys, Eastwood made his first lasting impact as the Man With No Name in the Spaghetti Westerns he starred in in the '60s. His rugged charm was solidified through his his raspy authoritative voice, narrow eyes, use of trademark expressions, and the occasional unexpected smile. If you're doubting his style, then you may just cross the line and make his day, punk.
