No stranger to a ten gallon hat or a pair of chaps, Clint Eastwood has appeared in landmark Western movies from the ’60s (The Good, the Bad and the Ugly) through the ’90s (Unforgiven). But his breakout role in the genre wasn’t on the big screen. It was on TV in the late ’50s when he played ladies’ man Rowdy Yates in Rawhide. Starting on Sat., Apr. 20, AMC will air the popular western series every Saturday morning as part of AMC Cowboys. Can’t wait? Here are shots of a very young Eastwood in the role that would make him a star.
