Actress Danner Brown was cast to play Katelyn Pavey, despite having both her arms, because of her resemblance to Pavey. The real-life Katelyn acted as a body double in some scenes. So, the actress who played her had to look "enough like Katelyn that the real-life Katelyn could be the body double." They eventually chose Danner Brown for the part. "She has the same color hair. They're virtually the same height," director Tyler Sansom said. "They just look very similar, just not in the face. We had to do some movie magic on that one."
