Whether you were there on November 15, 2013, or if you just heard about it on the news, nearly everyone in the world was moved by the adventures of Batkid in San Francisco. Now the new documentary Batkid Begins tells the whole story, from cowl to cape. It begins with Miles Scott, a northern California kid who was diagnosed with leukemia at 18 months of age. Miles missed out on a normal childhood as he underwent a series of brutal treatments. During that time he discovered Batman, via TV reruns of the 1960s series, and became a fan. When the Make-A-Wish Foundation determined that Miles qualified for a wish, he decided to be Batman. Patricia Wilson, the executive director of the San Francisco chapter of Make-A-Wish, went into action. The day was planned as a series of rescues, chases, and collars, which only grew more and more complex.
