Last November saw the city of San Francisco changed into Gotham City for Miles Scott, a young boy who was diagnosed with leukemia at an early age.
Little Miles was transformed into Batkid and took over the streets of Gotham fighting the likes of the Riddler, the Penguin and the Joker, with the help of the Make A Wish Foundation.
Now a documentary is being made about the event.
Award-winning filmmaker Dana Nachman is taking Miles Scott's Batkid story and creating a feature-length documentary, which is being funded by crowd-sourcing from IndieGoGo.
Check out the Batkid Begins trailer:
