Boots Southerland (born Marlin Southerland, c. 1955, raised on a ranch in Manzanola, Colorado) is an American actor, stunt performer, and wrangler of 34 years in the film industry. He served in the U.S. Navy as a Flight Deck Aircraft Director on the USS Hancock (1964–1967, Vietnam) before moving to New Mexico in 1970, where he trained horses for stunt work — falling, rearing, and stagecoach driving — which led to his entry into the New Mexico film industry as a horse wrangler, stunt performer, and actor. He continues to work in all three capacities. His most notable film credits include a "managerial" victim in No Country for Old Men (2007, directed by the Coen Brothers, with Tommy Lee Jones), Marshal Fred White in Wyatt Earp (1994, with Kevin Costner), a Warden in Terminator Salvation (2009), US Marshal Keith in Sicario (2015), Marshall in Jane Got a Gun (2015, with Nicole Kidman and Jake Gyllenhaal), Outlaw (Buffalo Hunter) in Hostiles (2017, with Christian Bale), Sheriff in Those Who Wish Me Dead (2021, directed by Taylor Sheridan, with Angelina Jolie), and Sol in Dead Man's Hand (2023). On television he is best known as Wade Morrow in Yellowstone (2018–2020, 6 episodes, Paramount Network), with earlier credits in Lonesome Dove (1989, as Sergeant), Walker, Texas Ranger (1997–1999), The Magnificent Seven (1998), Preacher (2016), and Into the West (2005). He also did stunt work on The Hunger Games (2012) and served as a driver on Hell or High Water (2016) and Legion (2010).
