The movie's lead character, Claude Barbee, is actually named after the real life Texas outlaw who killed a Deputy in a gunfight on a west Texas ranch in the early 1900's. Barbee, whose brother was a Texas Ranger, fled before being captured, but escaped. He was pursued by Pat Garrett at one point, but gave the lawman the slip and made it out to California, where he lived under an assumed name until he died in 1949.
The crew reused several props, signs and construction left behind by the Coen brothers' True Grit (2010) remake in Granger, Texas. Production on the movie wrapped in Bartlett, Texas mere days before a giant courthouse facade was erected for "Willoughby" in the second season of NBC's Revolution (2012).
