You may remember this heart warming story from a few years ago, when the city of San Francisco, and thousands of people around the world, came together to make a 5-year-old Leukaemia patient Batkid for the day. Prepare yourselves for the documentary: Batkid Begins: The Wish Heard Around the World.
The documentary will follow the events of November 15 2013 as Miles becomes Batkid for the day. However, it will also look at how a simple wish to the Make-A-Wish Foundation ended up becoming a global news story.
Batkid Begins will release June 26 and you can watch the first trailer for it below:
