Due to his tight schedule with Star Trek: Beyond (2016), Chris Pine was only available for two and a half weeks, so all his scenes had to be shot very rapidly and in sequence to maintain the required level of energy.

The first two bank robberies take place in Archer City and Olney, Texas. These were towns used in the filming of The Last Picture Show (1971), which also starred Jeff Bridges.

Taylor Sheridan's uncle, McLennan County Sheriff Parnell McNamara, served as a consultant to Jeff Bridges on the shoot. McNamara had been a U.S. Marshall for over 30 years.
