The movie was very upbeat at the end, and had a typical Hollywood happily ever after ending. The reality may have been quite different. Rather than having a happy marriage with the woman who had been his nurse, Mary Carr, things appear to have been far from rosy. She had been a prostitute, an alcoholic, and may have contributed to his early death. According to Christy's brother, Mary moved Christy away from his family and neglected him. It is hard to know whether these allegations are true, but I have attached a news article about the story.
