batkid begins trailerThe world was captivated last November when 5-year-old leukemia survivor Miles Scott took to the streets of San Francisco as Batkid, fulfilling his dream of becoming Batman through the Make-A-Wish Foundation. Now, a documentary about how that event came together is currently in production, and a new trailer has debuted.

"Batkid Begins" reveals Miles's lifelong love of superheroes, and how his request to the Make-A-Wish Foundation of the Greater Bay Area morphed a simple dream into a cultural phenomenon. Make-A-Wish execs discuss the painstaking detail with which the event was planned, including choreographing actors to play the bad guys, building a custom car seat for Miles in a Batmobile, and drawing tens of thousands of people to transform San Francisco into Gotham, and its citizens into screaming, supportive fans of the pint-sized crime fighter.

We dare you to watch the trailer without breaking out into a huge grin. This is one of those stories that's so heartwarming that it really does, as the trailer explains, restore your faith in the human spirit. And we wouldn't blame you for shedding a tear or two, either.

"Batkid Begins" is currently seeking funding through an Indiegogo campaign. The project, the brainchild of filmmaker Dana Nachman, is nearly halfway to its $100,000 goal with 22 days left.
