On Nov. 15, 2013, Miles Scott, a 5-year-old cancer survivor, officially donned the cape and cowl and became "Batkid."

For that one day, thanks to the efforts of the Make-A-Wish Foundation, Batkid became the savior of San Francisco, nabbing both the villainous Riddler and Penguin and standing tall in front of tens of thousands of cheering citizens. It was, and still is, one of the most heartwarming, tear-inducing, humanity-reaffirming moments I've ever had the pleasure of covering. And thankfully, this inspiring story is now coming to a theater near you, thanks to filmmaker Dana Nachman.

"The fact that thousands of people took their adult hats off that day and acted like kids really appeals to me," the director told IndieWire earlier this year. "I try to look at life from the perspective of a child, with that kind of openness, as much as possible. This story, and now this film, really embodies that mindset."

Nachman and her crew document the back story and lead up to Mile's big day, relying on the footage shot by the Foundation for the big Act III. The quality of this last piece of the puzzle, she told Ramascreen, made her job infinitely easier. 

"I didn’t have high hopes really; I thought maybe they would’ve had a handheld or whatever, but they actually shot it with a crew of three cameras and two go-pros and so five total cameras," she said. "So when you see the trailer, the video’s awesome, so that’s the bulk of our video for act 3."

Grab a box of tissues and check out the trailer below. "Batkid Begins" opens in limited release on June 26.
