Liam Neeson and Pierce Brosnan said they had the most fun in their career making this film. They loved westerns as kids, and were thrilled to finally to be in one.
Pierce Brosnan is on-screen for most of the first fifteen minutes of the movie, but he doesn't speak his first word until thirteen minutes and fifteen seconds in. Until then, he just grunts, groans, and screams of pain.
Xander Berkeley is an American who plays an Irishman. Liam Neeson and Pierce Brosnan are Irishmen who play Americans. Anjelica Huston lived in Ireland for a lot of her youth, and holds Irish citizenship.
In Jewish and Christian theology, a seraphim is a type of angel. One could conclude the two main characters are angels that have fallen from grace. They battle each other from the mountain tops (Heaven) to the hot desert (Hell).
Had a forty-five-day shoot.
