Something worth fighting for: The definitive ranking of Yellowstone mustaches

8. Jim Courtright — 1883

Played by: Billy Bob Thornton

Mustache Style: Petite Handlebar

Billy Bob Thornton has done some exceptional mustache work throughout his career and he certainly brings the heat to his brief appearance in 1883 as Sheriff Jim Courtright. His mustache here is accompanied by a beard but the heft, volume and distinct styling render it an independent entity worthy of recognition.

Due to his prolific acting credits, Thornton is almost instantly recognizable in any role. But here, the mustache is interesting enough and unique enough (for him) that allows him to blend into the role and not be distracting as a cameo.

7. Zane Davis — 1923

Played by: Brian Geraghty

Mustache Style: Chevron/Walrus

Brian Geraghty, the actor who plays ranch foreman Zane Davis, has one of Hollywood’s most underrated baby faces. He’s 48 but looks almost exactly the same as he did 17 years ago in We Are Marshall when he, at 31, easily passed for a college underclassman. His ineffable youth could have made him an enormous casting risk, especially in a role as a rough, capable and experienced ranch hand. But his trim mustache does a lot of work in aging him believably, setting up one of the most compelling supporting performances in 1923.
