Ben Affleck, who will don a bulky Batman suit in the upcoming Batman v Superman: Dawn of Justice movie, said so himself. Batkid is the "best Batman ever." Sorry, Christian Bale, George Clooney, Val Kilmer, Michael Keaton and every other Batsuit filler ever.
Batkid is Miles Scott, a leukemia survivor who last year when he was 5 years old "saved Gotham" as part of his Make-a-Wish Foundation dream wish.

Now, filmmaker Dana Nachman and KTF Films are completing a documentary to capture the ins and outs of Batkid's big day that brought thousands of people onto the makeshift Gotham streets in San Francisco to watch him thwart the Penguin and the Riddler.
Titled Batkid Begins, the documentary needs help before it can debut. The project's team is trying to raise $100,000 to pay for aerial footage of San Francisco, a soundtrack, music licensing, editing and special effects. So far, people have donated more than $47,000 on Indiegogo, with 23 days left in the campaign.

Batkid's valiant efforts attracted high praise from Affleck on Twitter, countless people on social media and even U.S. President Barack Obama on Vine.
"One thing that struck me was how many people were holding up signs saying, 'Save Us, Batkid,' and I looked at those signs and I thought, 'You mean that literally,'" Mashable's deputy editor Chris Taylor says in the trailer. "In helping him to live this dream, we were saving ourselves. We wonder why we're not happy a lot of the time, and it's because we forget this sort of thing. But here was an event that forced us to remember."
The trailer debuted at Comic-Con San Diego before arriving on YouTube.
