Kiefer Sutherland was so anxious about filming his first scene opposite his father Donald Sutherland that he couldn't sleep the night before the shoot. Upon reporting to the set Sutherland Jr. bashfully admitted to his father that he didn't sleep at all the night before and hoped he could give a good performance. Sutherland Sr. laughed and said he hadn't slept in day.
Kiefer Sutherland was motivated to craft a film that he could do with his father Donald, so he enlisted writer Brad Mirman to write a western story about a father and son, to be played on screen by a father and son. Kiefer claimed that they had waited years for the right script to come along, but with Donald approaching 80 it was the point that they felt it had to be done sooner rather than later.
Kiefer Sutherland figured that the filming of this movie was the longest amount of unbroken time he had spent together with his father in his whole life. Sutherland added it was enormously satisfying and gratifying being able to spend time with his father acting, something they both love and are passionate about, instead of "a fishing trip"
The movie was shot at the CL Ranch of Calgary, Alberta right after Discovery Channel's Klondike (2014) had wrapped, meaning the town had to be quickly transformed from a booming city circa 1890 to a not-so-booming town in the wild west circa 1870.
This will be the second film in which Donald Sutherland and his son, Kiefer Sutherland, are in scenes together. Both Sutherlands shared brief screen time together in the 1983 film Max Dugan Returns (1983) (which was Kiefer Sutherland's film debut). They also both starred in A Time to Kill (1996), though did not act together in that film.
