During the course of the shoot, writer-director Taylor Sheridan was visited on set by some Shoshone tribal leaders who astonished him with the revelation that, at that very time, there were 12 unsolved murders of young women on a reservation of about 6,000 people. Due to a 1978 landmark government ruling (Oliphant v. Suquamish), the Supreme Court stripped tribes of the right to arrest and prosecute non-Indians who commit crimes on Indian land. If neither victim nor perpetrator are Indian, a county or state officer must make the arrest. If the perpetrator is non-Indian and the victim an enrolled member, only a federally-certified agent has that right. If the opposite is true, a tribal officer can make the arrest, but the case must still go to federal court. This quagmire creates a jurisdictional nightmare by choking up the legal process on reservations to such a degree, many criminals go unpunished indefinitely for serious crimes.

Elizabeth Olsen experienced snowblindness while shooting the film.

Filmed on location in Park City, Utah. Coincidentally, the film would go on to have its world premiere in Park City at the 2017 Sundance Film Festival.

The film received a lengthy 8 minutes standing ovation at the end of its premiere in the Un Certain Regard competition of the Cannes film festival.

It took 40 days for the shoot to complete.

Jeremy Renner was the director's first choice for the lead role but as he was busy shooting Arrival (2016) at that time, Taylor Sheridan approached Chris Pine who later had to drop out because of his role in Wonder Woman (2017). Coincidentally, Renner's schedule opened up and was roped in for the role.

Wind River Indian Reservation is the seventh-largest Indian reservation in the U.S.

The final installment in Taylor Sheridan's thematic American Frontier trilogy (the other films being Sicario (2015) and Hell or High Water (2016)).

In order to get attention for the movie so that Taylor Sheridan could get enough money to finish it in post production the way he wanted, he entered it into Sundance without telling his producers, who he says were not happy because they were trying to close a deal with TWC for the film. Nevertheless, that deal was eventually made.

Taylor Sheridan's first screenplay which he didn't write on spec. Sicario and Hell or High Water were written on spec.

The film is based on actual events.

The grueling location shoot was filmed in real blizzardy conditions with crew and equipment being primarily ferried to locations on snowmobiles and snowcats, since regular vehicles were totally unsuitable for the hazardous terrain. Cleaning up unsightly vehicular tracks left in the snowy landscape had to be done with some compositing in post to keep the vista in 'virginal' condition.

The Wind River reservation is a real Indian reservation, and was also featured in the CW television show Ringer (2011-2012), starring Sarah Michelle Gellar.

This is Elizabeth Olsen and Jeremy Renner's third time working together on a movie, after Avengers: Age of Ultron (2015), and Captain America: Civil War (2016).

Gil Birmingham, Julia Jones, and Graham Greene have all had a role in the Twilight series playing characters from the Quileute tribe.
