Despite conquering many genres in Hollywood, there are several iconic directors who have never made a Western movie. The popularity of Westerns ebbs and flows over time, and while the genre is certainly not as successful as it was when it dominated the box office from the '40s to the '60s, there was a time when most of Hollywood's legendary directors not only cut their teeth on Westerns but made their fame and fortune from them over their entire career. These days, it isn't a requirement to make a Western the way it used to be when the genre was in its heyday.
