Batkid became a viral sensation last November, when 5-year-old Miles Scott had his wish fulfilled to become a superhero and save all of San Francisco from a cadre of evil villains. His story is retold in the upcoming documentary Batkid Begins, which brings this heartwarming tale to life on the big screen. Check out the first footage, which debuted today at Comic-Con as the San Diego festivities begin to wind down. Batkid lives!

One child. One wish. Millions moved. Batkid Begins takes SF & the world on his quest to conquer evil.

'Batkid Begins' follows the events leading up to the day Batkid saved San Francisco and what happens when an event goes unintentionally viral. The goal that day was to get a couple hundred people to show up to support Miles Scott and his wish to become Batkid, after battling leukemia for more than half his short life.

The thought was a crowd of 200 would seem huge to a five-year-old boy, but what happened next blew everyone's minds. Support for the idea of granting Miles's wish kept pouring in and soon it was clear that the crowd would be much bigger than the modest expectations.

Instead of a few hundred, 25,000 people lined the streets to cheer Miles on as he saved Gotham. The superhero spirit spilled onto the Internet as news of Batkid's heroics reached over 2 billion people, touching hearts around the world. Batkid was impossible to miss that day as we were glued to our computers, phones, and in San Francisco, our office windows trying to be a part of the celebration.
