In a 2018 interview, Guy Pearce said that this is his favorite of all of the movies he's ever done.
The wardrobe was handmade to be as authentic as possible, and even the buttons were all handmade for this movie.
All the firearms are period replicas. Famed gunsmith Buck Merry crafted each one with his own two hands. They were indeed transported to set via steam locomotive.
Originally, Director John Hillcoat approached Nick Cave about doing the soundtrack for a western. Eventually, he asked if Cave would write the screenplay as well.
