Miles Scott, a 5-year-old American boy, was diagnosed with leukemia at the age of one and a half. He decided to face the disease bravely like his favorite superhero, Batman, against the bad guys. People who knew about it decided to help him realize his dream: on November 15, 2013, with the help of the whole city of San Francisco, he became Batman again. The story will be made into a documentary "BatkidBegins (corresponding to BatmanBegins)," and director Dana Nachman announced at this year's San Diego Comic-Con that she plans to raise $100000 to complete the documentary.
