James Horner collaborated on this film after he and Antoine Fuqua became close friends while making Southpaw (2015). According to Fuqua, Horner's team visited him on the film's set in Baton Rouge, one month after Horner's accidental death, to deliver the completed score. Horner had been so inspired after reading the script that he composed the entire score during pre-production.
One of the few Western movies where an actor's ethnicity matches their character's. 'Lee Byung-hun' is East Asian (Korean). 'Martin Sensmeier' is Native Alaskan (Tlingit). Manuel Garcia-Rulfo was born in Guadalajara, Mexico.
According to director Antoine Fuqua, one of the reasons that Martin Sensmeier was cast as Native American Red Harvest was that Sensmeier had luxuriant, almost knee-length hair when he auditioned. Not having been told that this had been a selling point, Sensemeier cut his hair shortly thereafter. Fuqua was originally upset, but then had the idea for Sensmeier to have his hair cut into a Mohawk, which fortunately also turned out to be historically accurate.
When Red Harvest first appears he speaks in Comanche, the language of his character. However when he states "my name is Red Harvest", he says this line in Tlingit, the language of Sensmeier's real Native people.
Later in the movie, Chris Pratt uses a shortened lever action rifle. This unique firearm, the mare's leg, was made popular by Steve McQueen in his series Wanted: Dead or Alive (1958). Pratt's character is McQueen's character from the original movie.

Wagner Moura was originally cast as Vasquez. The role was recast because he was committed to film the Netflix show Narcos, where he plays Pablo Escobar.
The characters use explosives produced by the Giant Powder Company of San Francisco. The company began operations in 1868 as the United States' first manufacturer of dynamite under exclusive license granted personally by Alfred Nobel.
Denzel Washington and Chris Pratt were the first two actors cast. Antoine Fuqua knew that both men have expressed interest in appearing in a western film. Getting Washington was easy but Fuqua initially was unsure which role that Pratt fits in. On the second phone call between Fuqua and Pratt, the latter started to sing "Oh Shenandoah", which Fuqua immediately declared that "Pratt is Steve McQueen".
Bogue's line, "If God didn't want them sheared, he would not have made them sheep" echo's Calvera's "If God didn't want them slaughtered, he wouldn't have made them sheep" in the 1960 version.
