Chris's son, Christopher, says he doesn't remember much about life on the street. "I didn't know we were homeless. I just remember that we were doing a whole lot of moving," says Christopher, who is now 25 years old. "I just know that when I looked up, he was there. I looked around, he was there."

Chris says he worked hard to create a sense of normalcy for Christopher. "We may not have known where we were going, where we were going to eat, or where we were going to sleep, but we were together every day," Chris says. "And there are probably a lot of folks whose children live in million-dollar houses who can't say that."

Christopher says he has seen the movie and thinks it's a wonderful homage to his father. "It's just a tribute to my dad," Christopher says. "My dad has a big heart and is kind-natured. So it was awesome."
