When Arthur RedCloud answered an online casting call for this film, he thought that it was for a small role. He never imagined that the role was a very pivotal one. It wasn't until he was called to Canada to audition for director Alejandro G. Iñárritu and first set foot on set that he realized how important his role really was. He says, "You usually have to get a small part on a major film and then work your way to a huge major role, especially working with a director like that, as well as an actor like Mr. DiCaprio."
